Hello, my name is Max Nicotra, Technical Marketing in the America region for Teseo modules. Today I'm giving a refresher and update on ST GENESIS module family, Teseo Live 3, for the industrial T-positioning applications. I will introduce the ST Teseo big three family of GENESIS positioning modules and some of their many features that make ChemoGrip fit for mobility applications. After that, my colleague, Mike Slate, will provide an overview of our Teseo that reckoning draw-drawn solutions. In the last banal list, Bas Mamo, CEO of NavMedic, will present their Teseo Live 3F-based immobility solution and performance. Before getting into the Live 3 module details, I want to give an overview of the Teseo 3 chip set, architectural features. Given that the Teseo 3 chip set is the heart of Live 3 and Big 3 modules. So what is the Teseo? The Teseo is a GENESIS chip set family that leverages simultaneous multi-constellations to provide workplace GENESIS receiver performance for the numerous location-aware applications and it is automated rate certified. The Teseo 3 is a SOC, single-banded one multi-constellation that integrates considerable hardware functionality, as you can see in this chip block diagram. Starting from upper right, going counterclockwise, satellite signals come into the green block, which is the RF interface, which down converts the GPS satellites, 1.5 gigahertz signals to IF, four megahertz, which ADC samples and converts to three bits signal and magnitude data with AGC, automatic gain control. This data is sent to the white block or baseband DSP colorador engine, which does an early late type of correlation on the baseband signal and magnitude data to perform low-level acquisition and tracking. This correlation result and decoded navigation data are passed to the R9 core for position computation and uses the 256K young chip graph. Let's dive into the Live3 module family overview. So, the Teseo Live3 GENESIS module family is available in two flowers, the Teseo Live3F and the Teseo Live3R. The Teseo Live3F and the Teseo Live3R modules embed the Teseo3, which supports simultaneous of three constellations, GPS and Galileo, and neither Glonas or Baidu. They also support SBAS. The Teseo Live3F and the Teseo Live3R are the first members of the Teseo Live module family, enabling faster time to market with the same great performance and many features of the Teseo chip set. The Teseo Live3F is our best in class multi-concelation GENESIS module with outstanding accuracy for IoT ecosystems, good tracking, flip management application, and et cetera. The Teseo Live3F and the Teseo Live3R are intended only for industrial, consumer, and IoT applications. In the center is the module silhouette of, so sorry, in the center is this module silhouette. On the left is the list of the key features on the right to corresponding benefits. The multi-concelation with increased availability, redundancy, improves the tracking in a certain environment is often the case in urban or foliar areas and improves the special distribution of visible satellites, resulting in improved dilution of precision or DOP is beneficial to have a best-in-class accuracy. There are several versatile low-power modes allow tellering and GENESIS usage to application-specific needs and power budgets, assist the GENESIS to reduce the time to first fix, pre-load the functions, geofencing of the meter, data logging are useful basic functions for certain IoT applications. For example, people input trackers, fleet trackers, and insurance trackers. Pre-certified RF modules, Live3 modules are compliant with several RF certifications to reduce the sign risks, costs, and time. And Live3F executes firmware auto flash, which has two big benefits. The first, it enables firmware configuration changes to modify and expand the end product's capability. And second, it enables firmware upgrades throughout the product's lifecycle to improve performance and extend product longevity. Obviously, Live3R does not support all flash-based features. So both the Live3F and Live3R are a tiny, mid-less chip carrier or LCC 18-pin package. The module has three supply voltage lines, VCC, VCCIO, and VBAT at 3.3 volt, and the image below stated shows the Live3F architecture. In the center is the Live3F chip. Upper left, 26 megahertz DC oscillator for fast time to first fix. 32 kilohertz RTC for maintaining accurate time. And upper right, 16 megabit embedded flash for software execution and data storage. Reset and wake up inputs from host, PPS output to host, and UART, I2C, slave communication interfaces to host. Live3R has the same architecture Live3F by the flash. The modules allow to get a very simple design with a minimal BOM. So filter is optional, but recommended for the sign with collocated communication ICs. And the LNA is optional, but recommended for passive antenna designs. And the Live3F hardware user manual, which is available on st.com, provides complete information to support your design. Here are the evaluation boards. The XNUCLEO is ideal for STM22-based prototyping with a comfortable NMEA message output and command input over UART or I2C slave communication interfaces. It is available only for Live3F. EBB Live3F and EBB Live3R allow a complete evaluation, including power consumption measurement. All these evaluation boards are audible on st.com and through distribution. This is a free Windows PC-based GUI tool that is extremely powerful and easy to use. It is possible view, record, and playback NMEA messages, also for debugging, view graphics such as position, sky view, view and character noise ratio, send commands, and upgrade and configure the firmware. Let's dive now into the new GNSS positioning module family for mobility applications. The ZeoBig3D GNSS module family is available in two flowers, the ZeoBig3DA automotive grade for automotive market, and the ZeoBig3D industrial grade for aftermarket. The ZeoBig3DA and the ZeoBig3D are the first two members of the ZeoBig module family. They enable faster time to market with the same great performance and many features of the Zeo. Three chipset and support SD draw, that reckoning algorithm which arguments the position accuracy and availability, especially when the GNSS signal is degraded by environmental conditions such as tunnels, urban canyons, indoor parking, and multi-level highways. Draw, exploit the integrated SD6 axis IMU, 3D accelerometer and 3D gyroscope, which is automotive grade certified in Big 3DA. Here are the same considerations made previously applied. Both modules support simultaneous three constellations, GPS and Galileo in either GLONUS or Baidu, and support also the SBUS, satellite-based augmentation system. Several versatile low-power mods, low-tailoring GNSS usage to application-specific needs of our budgets, assist the GNSS to reduce time to first fix, and both modules execute a lot of flash which has the same two big benefits, enables firmware configuration changes to modify and extend the end product's capabilities. And second, it enables the firmware upgrades throughout the product life cycle to improve and extend product longevity. Big modules are tiny, shielded, little less, chip carrier or LCC, 24-pin package. The modules have three supply voltages line, BCC and BCCIO at 3.3 volt, and we bet in the range of 2.1 to 4.3 volt. At the C oscillator for fast to time first fix and RTC oscillator for maintaining accurate time for hot start fixes are integrated in the modules. A flash memory for software execution and data storage is embedded into the CO3 chip set. On the right lies the big three pinout. Pin 15 up to the left and pin 4 lower right are the signals relating to the automator. Pin 4 forward vehicle direction input pin, binary value forward or backward, and polarity is selectable. And pin 15, the will tick, automator input pin. Big 3D modules make prototyping quick and easy with a minimal BOM. On the left you find the automator signals, which are optional but preferred if available. The automator data can be provided over wire by pin 4 and pin 15 or yours. In this case the external host fits the big 3DA with will tick data via NMEA, NMEA input message. So fielded optional but recommended for the sign we call located communication ICs and LNA optional but recommended for placebo antenna designs. The big three hardware and software user manuals on our website provide complete information to support your design. A GNSS function is used to avoid cold start after four hours and warm start between two and four hours by predicting the position does reducing time to first fix from around 30 seconds down to one to four seconds. These are three, there are three modes. Self-train with computation being done on chip in a background task. The prediction works well if I'm not moving under different satellites say 61 miles or 100 km away. The predicted is a lighter computational load to the around 12 kilobyte packet download via TCP IP. It works everywhere, download the family's data typically every 14 days. And the last one, real time, works everywhere, download the family's data typically every two hours if I'm not moving more than 61 miles or 100 km away since the last download. Low power mods. Adapting, it works in raw mode. And if the GNSS module is tracking several satellites being part of different constellations, it could be possible that the contribution of some of them to the accurate position measurement is marginal or nonexistent. In this situation, the system can decide to turn off a constellation of constellations. The estimated horizontal position error, EHB, is the discriminant parameter. Cycle, it works in raw mode. The position is calculated each second. DRF and baseband are turned off to the 70% of the run time. Pre-order fix, it works in GPS only. After the preprogrammed time, the lift 3F wakes up, calculates the fix and moves back to standby. The last one is the fix on demand. It is connected to an external event. For example, let's imagine a system which is supposed to be still an accelerometer connected to an external host detects a movement and the host wakes up the lift 3 to recalculate the fix. The module operates using the last save configuration. Here are some draw-and-dram related features. I will let Mike to introduce them during the second part of this presentation. There are three standard pre-order functions. Detalogging, this memory is part of the flash. Integrated to the ZO3 chip set, which is hosted in the VIC-3 module. Geofencing, there are up to eight configurable circles and odometer. It provides infinite travel distance, but is not a step counting. The EBB VIC-3DA evaluation board is a complete standalone evaluation platform for the ZO3DA and the ZO3D that reckon genesis module for features evaluation and also for power consumption measurement. To find out more about the ZO genesis module families, live3 and VIC-3, as well as get access to permanent technical documentation in the ZO suite, go to www.steve.com slash genesis modules. VIC-3D modules will be available in Q1 2021. I recommend you join us in the SD genesis community to share ideas and ask questions. Thanks for your time. Now I want to hand over to Mike, who will provide an overview of our debt-recony draw-dram solution. Thanks again. Bye. Thank you, Max. Hello, everybody. I am Mike Slade, and I am the technical marketing leading for the ST Tessio positioning solutions. And I'm really excited to be able to share more details about the Tessio debt-recony solution that Max mentioned, which is a core feature of those Tessio VIC modules that we are offering soon to the market, making them really the best fit for all types of mobility and tracking applications. And I actually want to mention that this presentation was primarily generated by my esteemed colleague, Nicola Paola, who leads the navigation systems development team out of our Agrate Italy office. So I'm going to start it off with a poll question. The first one is, do your products currently leverage GNSS technology? So I'd love to hear from you since the polls and the Q&A at the end are really our only tools to make this a dialogue instead of a monologue. So I would greatly appreciate it if you could each take a few seconds to answer the poll. So debt-recony, commonly referred to simply as DR, perpetuates position, velocity, and attitude when GNSS is either, one, not available, for example, when in tunnels or parking garages or other areas where there's a complete loss of satellite signal, or two, when GNSS is available but not accurate due to reflective or widely obscured environments such as in big cities with a lot of tall buildings, as you can see in this picture, which we uneffectually refer to as an urban canyon. And that's because really all the medium and low-angle signals have trouble directly reaching the street where the user typically is located. So shown in this diagram on the left, you see its draw, our debt-recony automotive way, which is a Coleman filter-based algorithm that estimates position, velocity, and attitude using various sensor inputs. So from the top of that left diagram, you'll see, going clockwise, those sensors are HIRO for YAR heading, an odometer for distance traveled, an accelerometer for pitch, temperature, and most important, the GNSS, which is considered an input because it is used to calibrate the draw algorithm.  Then shown in the diagram on the right, you see drum or debt-recony unplugged mode is also a Coleman filter-based algorithm that estimates position, attitude, and velocity. Using the same sensor inputs, as you can see, except one's missing. In the upper right, it's the odometer, hence the namesake unplugged, as it does not require a direct connection to the vehicle. And it is really more a fit for aftermarket applications and various mobility-specific applications. So drum, in turn, computes distance traveled from linear displacement of the accelerometer. The key to draw and drum performance is the 6-axis IMU. We highly recommend the STASM330LHH for best automotive performance or it's industrial equivalent for that, which is the ISM330LHH or the LSM6DSR. So Tessio drum, I want to talk about a little bit more its specific advantages or value add features for navigation, telematics, and mobility. Automatic temperature compensation, or ATC, is what actively compensates for thermal effects to the IMU, guaranteeing long-term accuracy. Automatic free mount, or AFM, autonomously determines and accounts for PCB installation of the end product, guaranteeing consistent optimal performance independent of how it's mounted in the vehicle. MATMAGE feedback, or MMFB, allows map data from the end application to be fed back to draw and drum to still improve navigation accuracy more so. Low-level interface, or LLI, enables the solution's position, velocity, and attitude, and time, in fact, that output at a rate of up to 20 hertz, and also an IMU data output at a rate of up to 100 hertz, all with minimum latency and jitter for absolute accuracy. And lastly, not shown here, but also available is sensor over UR. So it is offered for architectures where the IMU is not directly connected to Tessio. Hence the sensor data is gathered by an external processor and sent to Tessio via UR. Drum performs the same computation and with minimal latency and jitter from that host data, ideally less than 10% of its delay or transmission time, an accurate PVT can be provided. So this flow diagram is a high-level overview of the drum fusion filter. It depicts system inputs such as raw GNSS measurement data in the upper left and raw IMU data in the lower right. And the Tessio firmware keeps both the GNSS and IMU data perfectly synchronized. In other words, we have a sensor input data handling and buffering routine that's optimized for minimal latency and jitter as I mentioned before. And what it does is it enables very quick an accurate sensor calibration and ultimately an optimal fuse navigation output. On the right, you can see a list of output states and position velocity and attitude are the primary output states which represent the dynamic system of interest, which in this case is a vehicle. And then there's some secondary output states that consist of IMU calibration parameters, IMU installation angles and others not shown. Essentially, the system estimate is driven by the sensor's input in the loop to the right of that diagram in the middle you see. And that from 20 to up to 100 hertz depending on the actual system, meaning to be modeled and how dynamic that system is, meaning vehicles such as cars are not as highly dynamic as drones. So this system estimate is concurrently being corrected by the left loop, which is the one hertz GNSS fixes. And that's of course when, like I said, it's available since GNSS is not always available like in a tunnel or it's constructed in a city. So the green boxes you see in this diagram represent the system equation matrices and K represents the common game matrices which optimally controls the current observations as they vary within specified tolerances or what we call covariance limits. The established, well-established common theory dictates that the modeling of both sensor measurement noise in the R matrix and process noise in the Q matrix also be taken into account. So the crux of the matter is this sensor fusion or common has to be calibrated, has to be calibrated quickly and maintain an accurate state estimate. So from very first power up of an ECU for example in a brand new car, the new is mounted however the design dictated and the gravity vector is quickly determined while the vehicle's static and position on the road. So the orientation of the three axises of both the gyro and accelerometer become known with respect to gravity in that vehicle supporting now the subsequent DR computations and after some initial driving course or rough initial calibrations refined or the gyro by executing some turns which is what helps us dial in the yaw parameters and for the accelerometer by executing some straight driving and dialing in that accurate linear displacement calculation of distance traveled. So good GNSS is actually required as a reference during this calibration period but then these common states like I mentioned are periodically recorded to MDM and that power down so that at subsequent power cycles of the vehicle over the life of the vehicle the states are extracted from MDM and at every power up and the solution retains that fine or very accurate calibration that's already learned for this vehicle over the life of the vehicle maintaining that the DR performance doesn't vary from time to time. It is consistent and continually improving. So thank you for answering our first poll question the responses to do your products currently leveraged GNSS technology makes me think oops I apologize makes me think several are just learning about it so that's good to know I'll tailor kind of my discussion that some for sure use it or in development or future plans so it's good to see it's good to see this is quite an even distribution so of course you know for those of you are in development or future plans by all means you'd be glad to discuss in after this with whom your requirements and see how we can help you achieve the addition of GNSS to your solution. Here is the second and last poll question of the day and it is if your product does require GNSS what are your three requirements and again I'd love to hear from you since this question gets more to the heart of what your application needs from GNSS. So just wanted to talk a little bit about the IMU that I mentioned before the ASM 330 LHH which is a 6-axis IMU and it's been designed from the ground up for automotive applications and it is actually qualified for AEC Q100 with an extended temperature range to positive 105 degrees C. The navigation accuracy is directly proportional to sensor noise and temperature dependence so that all invariance commonly known method is used to characterize low frequency noise which impacts this navigation accuracy over longer integration periods and in the lower left you see the stability features listed that show a value of 3 degrees per hour for bias instability or EI and 0.21 degrees per root hour for angle of random walker ARW which if you're not sure how those compare they are best in class and in fact ST is the only manufacturer to publish BI and ARW in our data sheet which reaffirms our confidence in being best in class and as I mentioned for industrial designs by all means the ISM 330 LHH is a lower cost equivalent solution. So I just wanted now to share a little more real data and this is the first of a couple slides. This is a snapshot of a recent competitive performance comparison in two very different environments. First off on the left is the open sky environment or highways which typically weight GNSS in the fusion solution more heavily because the GNSS signal is so good in highway and open sky that many signals are available there's few reflections and as you can see the circular error probable or CEP 50% error is approximately 1.4 meters in this environment. On the right, the second environment is urban canyon which typically weights DR more heavily due to GNSS, multi path reflections and obsecration it has to de-weight some of those questionable signals as I previously mentioned. So the CEP 50% position error is greater in this case it's about two times or approximately two meters two times the open sky that is due to lower availability of line of sight signals and generally weaker signals of GNSS. So our ST drum metrics in the blue bars versus competitors metrics in the pink bars indicates that drum has slightly better performance at CEP 50 and significantly better performance when we evaluate one and two centimeters. This is a snapshot of heavy foliage performance and I apologize it's a bit of an eye chart but I'll try to direct you. So the upper left plot shows several long sections of heavy foliage where the blue track depicts GNSS only positions and the light yellow between those blue depicts the three sections where GNSS signals are greatly degraded. And so if you look closely at each foliage exit and to do that you need to note that the vehicle is traveling from right to left in that picture and so from outage one to outage two to outage three as you can see the blue GNSS only position shows slightly higher position error for those first few sections after essentially it comes out of the heavy foliage or comes out of those yellow sections because once it exits and starts to see those GNSS signals more clearly again of course they're quickly being reacquired but in that brief period there is a little bit of I should say there's increased error but now looking at the lower right plot which is the same drive test but it's showing the red which is actually our fused position with GNSS and drum and again moving right to left of course you know through outages one two and three the white depicts the drum only track and in this case we've switched to pretty much drum only like a tunnel because the heavy foliage is that thick and again looking closely at each exit of those one two three foliage outage sections you do not see that greatly reduced position error because the drum has provided continuous tracking in the presence of weak GNSS signals so there's really not this gross error at the exit that demands reacquisition but instead the drum keeps a continuous position all through the route so this is an example how drum maintains that continuous lower tracking in all environments as designed to and needs to so this slide is a chart that shows position accuracy of the drum filter during a complete GNSS outage again it's based off a real field data using the ASM M330 LHH 6-axis IMU with actually our Tessio 3 solution and is the result of 30 test runs to ensure that there is statistical significance and the position error is simply expressed as a percent of a distance traveled in a tunnel the leftmost group of four bars shows one sigma errors for respective outage distances the middle group is 2 sigma and the rightmost is 3 sigma and as you would expect the percent error increases for 2 and 3 sigma but only linearly not exponentially confirming that the ASM 330 LHH is excellent performance with drum is bared out or out and so also you can see that the 4 kilometer tunnel performance is in some cases equivalent to or better than the half a kilometer which confirms that we still have this excellent bias instability and angle of random walk regardless of the duration because different tunnels have different durations so you really want to have as good short and long term duration performances you can get so we are looking at the response now to our second poll question and it looks like that cost as always cost is very important for sure and then power consumption so which makes sense because what we've seen as we DevCon appeals to more mass market or IOT applications so a lot of IOT applications are very power concern with power and cost for sure and so looks like performance and size are relatively comparable to so that's and that's what I would expect a fairly even balance a lot of times cost and power consumption are slightly bigger so again thank you for taking the time that helps us to know how to tailor our solutions so that they're the best fit for your application so again please do reach out to us after this presentation if you'd like to discuss your GNSS requirements in greater detail so thank you all very much for taking the time to learn more about our Tessio GNSS plus draw and drum solutions and of course the live and Vic modules that Max shared and to find out still more about the Tessio chipsets modules draw and drum or any of our products in that family line feel free to visit the ST.com slash GNSS modules landing page or ST.com slash GPS landing page so next I would like to introduce Boaz Mamo the CEO of Navmatic who is a valued ST partner who is developing solutions for micro mobility with various ST products such as Tessio thanks again bye thank you Mike and thank you Max for for giving us all this information I personally learned a lot from what you guys presented I present my name is Boaz and the CEO of Navmatic and we are focusing on high accuracy position for micro mobility now if we're talking about micro mobility what is micro mobility micro mobility is the solution of small vehicles that are usually replacing car rides in the distance of up to five miles it's what we all see in our cities like scooters and bikes, at usual electrics and from what we seeing today the micro mobility is a growing market it's a market that predicted to be like 500 billion dollars in almost 10 years and even today we see a huge growth in the sales in the interest of the audience in micro mobility and as much of this industry is booming and growing with the growth there is also coming a lot of problems and the problems that those companies are facing especially the shared mobility companies is around accuracy of position because first of all they have a lot of problems with regulators a lot of cities like Dallas and Copenhagen banned micro mobility from their cities because they don't like the people throwing it and parking it anywhere and that's caused a lot of problems to the micro mobility operators. The second thing is for operation personally and myself I started a company because I was trying to find a scooter and save time by getting my destination in a faster way and found out that I'm wasting more time looking for the scooter rather than to ride on it but when I worked on the solution I realized that operators also have a lot of problems to operate the scooters because they need to charge it every night and their employees need to find the scooters just can't find them because sometimes they can be a block away from where they can see it on the app with a more accurate position those operators find ways to create smart geofencing have a better rider experience and also been able to operate better their operation what we've pneumatic did we look for develop a solution that utilized existing sensors and new sensors that similar to the drum basically using IMU, speed data and GNSS data to generate a better location. Now the question is why do you need special dead rock name for micro mobility and the reason is that we found out that the physics of a scooter or a bike is very very different than a car a car you cannot lift and switch to 180 degrees on the other side turns are different there is so many different aspects between cars and micro mobility and therefore they needed to have a better DR dedicated for micro mobility the other thing that we added is our solution data we took correction service and we added it into the GNSS measurements in order to create a better measurements when we came into the solution we realized we need to have first of all some kind of evi kit that we want to test our solution and also shared with our potential customers and on the high level the things that we realized we need to have on the evi kit we added an MCU that obviously because the aiming for IoT needs to have as much of high performance as possible with low power we need a GNSS module that is going to be cheap but will enable us to have access to road measurements in order to implement the corrections we needed six axis IMU to make sure we had the accelerometer but also the gyroscope which is super important when you're having a scooter and we need to have a connector that can enable us to have a wheel tick or speed data to integrate in our solution and not least we need to have an internet connection in order to send our data to the cloud but also enable us to send our corrections to the device and when we looked into the existing solution we found in the ST kind of ecosystem the perfect match to all what we needed we used the nuclear STM32F7 to be our MCU we took the live3 GNSS module to enable us to have access to road data measurements and we took the six axis IMU from ST when we found out it's like the best performance for price that we can find out there especially for IoT applications this is how our EV kit looks like in real life and we found out that we also was really easy to build a custom shield that enabled us to change different modules that we need one of them for example we're looking now into the test CO5 also for higher performances in some of our customers and it makes it much easier to work and to change modules on existing shield this is our test scooter as you can see the red box on the bottom this is the system and above it obviously it's our grant truth system that enable us to understand the performances of our system and on the right you can see results from San Francisco over here you want we wouldn't be able to have a good grant truth system but we use the map in order to like see the performances of our system one interesting thing is that a lot of DR for example automotive using map matching is very fast that for scooters you can really use map matching because scooters can ride against traffic small alleys on sidewalks not necessarily riding on the road which makes it more challenging for the DR if you use map matching so we're not using map matching in this slide you can see results of our test in a standing scooter in a good really good up in sky performances based on the live 3 F receiver here you can see our test result in Santa Cruz which is pretty much light I would say over in environment and on the image you can see that the difference between the white line which is the genesis with our corrections and DR versus the yellow line which is what the genesis by itself performing and here you can see a test that we run in San Jose and you can see how the grant truth is the white line the green one is our solution and the red one is how genesis performing and you can see the big difference between how genesis performing versus our solution compared to that thank you very much for your time and for listening and I want to take this opportunity also to thank the SE team for the support to build that we needed a lot of support for the team and Mike and the team really help us to do that and if you have any questions we'll be happy to answer on them now thank you


The USI last week announced plans to campaign for better conditions for student teachers on placement. Along with various trade unions, they are calling for student teachers to receive payment while on placement to cover expenses such as travel, materials and accommodation. We ask student teachers on the St Patrick's campus what the main struggles are while on placement. We go out, we do eight weeks of placement, that's two months. The teacher that we teach for the full day and the teacher is still getting paid their full wage and the student teachers don't get anything. We still have to pay for our transportation, it's going to be in Dublin so we still have to pay for accommodation and then we still have to pay for our own resources. Basically when you're on placement you don't have like you're doing all your preparation for your lessons in the evenings and then you're going in teaching the next day so I don't know how people manage with like part-time jobs and stuff like I never was able to do it, was able to work through placement. Resources and everything is costly. Printing here, you put your point in about nearly five or every day just cover yourself so that's twenty-five or again like so it's all adding up like that's the main thing I suppose. That annoyed me for a while and still annoyed me, nothing's been done about it. DCUSU along with a number of other colleges are highlighting the campaign and are asking student teachers to fill out an online survey. DCUSU Vice President for Education and Placement Matt Davie is heavily involved in the campaign and is urging student teachers to voice their opinions. USA contacted me about the campaign and how I want to get involved and to be honest I jumped on it, I really wanted to do it, being a teacher myself it really affected me and being kind of representative for the biggest kind of cohort of teachers in the country in the Institute of Education on Pat's campus. We have the largest number of teachers there so it's really an issue that affects our students and so I wanted to be leading this with USA. I've done a survey myself with the four-tier Beds that went out so my class, we got a great response to that around forty or fifty percent of the course replied to that so we've gotten statistics from that as well and I've included them in the proposal that I'm currently making. I'm not sure about the closing date for the USA one but I presume it's going to be very similar information that I've already covered from my own survey that I did over the summer and so we're going to incorporate that into the proposal as well when we get the results from that I'm not sure the closing date though. Colleen Brady, DCU TV News Often named as one of the ugliest buildings in Dublin, the Fibsborough Shopping Centre is getting a makeover. New apartments that are expected to accommodate three hundred and forty students are set to be developed in Fibsborough as part of the 15 million euro redevelopment of the 1960 Shopping Centre. The scheme was approved by the council this month and was welcomed by DCU Student Union. Yeah, new shop accommodation is always welcome in Fibsborough so close. It's fantastic for us but the only thing I worry about is the pricing of it. I'm looking for compared to the one in the military that is for students but it's two hundred and forty nine euro a week so what I'd be worried about is would it be priced for a reasonable amount for a student or would it be overpriced? The price of student accommodation however is a concern. Seem as recent developments have rooms in Dublin costing a minimum of two hundred and forty nine euro a week. It's absolutely not fair like from my experience of renting I'm really really struggling especially at times like Christmas when everything is so much more expensive gifts for my presence and all this but I think the sad fact of it is is that if you go to college in Dublin Dublin is just an expensive place to live anyway not just for students for anyone buying them or renting so yeah I mean I think unfortunately just living in the capital is always going to be a bit more expensive. I'm looking since I still live at home but I have to commute to college daily and I find that expensive so I can't imagine how people are affording to live like away from home because they have to pay for their food and everything as well. My man pays for all that for me. I know I wouldn't be able to afford it anyway. It's definitely way too expensive and even now with all the new accommodation centres popping up they're like extortionate still so even though there's more and more becoming available it's still out of reach of a lot of people and it's definitely taken advantage of students as well because they know that they're desperate for accommodation and would do anything to be near their college so even though there's more now and it seems like we could do more for it I mean they could do more in terms of pricing and making it more affordable in general. Although many of the local people here are excited and supportive of the idea of the development some of them are concerned that the arrival of more students will also result in the arrival of more fast-food restaurants especially when there's already an abundance of them here in Pubsborough. Secondary schools are being hit by teacher shortages as many qualified graduates are moving abroad to work in the Middle East benefits include tax-free salaries and free living accommodation. Sheena Freel of the INTO gave her thoughts on why teachers are leaving. Well there are a number of factors I think really pay inequality is a big one that you know teachers aren't going they're not being paid and newly qualified teachers aren't getting the same pay as teachers who qualified a few years before them and I think the cost of living in Ireland is the cost of buying a house, the cost of getting a mortgage the cost of rent so for a teacher living in Ireland trying to pay rent and save money for a mortgage it's not feasible if you have the option choice between that or going to Dubai or Abu Dhabi for a couple of years and having the price of a deposit coming back it's an easy choice for teachers to make. At a time of rising enrollment in schools and huge demand for teachers many Irish teachers cannot afford to live and work in places such as Dublin and are choosing to take the skills elsewhere. Approximately 326,000 teachers worked in international schools in 2014. This figure is meant to rise in 2020 to 436,000. We spoke to a number of student teachers to see if they plan to work abroad. Yeah I definitely would because it's way better like you get free accommodation you get more money because it's tax free it's class because it's a different culture you get to see it all you get to travel it's a win-win place like Abu Dhabi and even England you get paid a lot more than you would over here for teaching so I'd probably go over there for a couple of years and then like build up money and then maybe come back here like I don't think I'd stay over there for the rest of my life like I would always probably come back home and teach. I think I'd prefer to stay at home you know I just kind of like Ireland did all my teaching practice here so I think I'd be a bit more comfortable teaching here and it means I can stay home with family and friends and that as well.  On Econody, DCUTV News. The business building in DCU, a place where many leading third students will hope to end up next year. However, as students fill out their CAOs, UCAS have announced that the numbers of virus students accepting places in UK universities has fallen by 11%. The fall-off doubled from last year and has been linked to concerns over an increase in fees after Brexit. Irish guidance councillors were caught as well advising students to study in the UK and the future of fees is unclear. There's a fear, I suppose, of the uncertainty. Economically and politically, students aren't quite sure what's going to happen in terms of the situation around fees, even the cost of living and there are so many variables going with that. So it's making students take stock. The advice that we would give as guidance councillors would be to do your sums, do your maths, to damage your parents and work out the logistics and the affordability. Can you afford to live and if the situation around fees, wherever you're going, changes, can you actually fund those fees going forward? English universities currently receive the highest number of Irish students opt-in to study abroad. However, this drop by 22% mastered just over 900. There's also fears over outbreaks that will affect the free fees scheme in Scotland and how this effect will impact the Irish students currently availing of them. So it's very hard to predict what's going to happen with the situation around Scotland. That could change. We just don't know what's going to happen. It's an unknown world at the moment. A dog is for life, not just for Christmas. That's the message from Dogs Trust as they launch their Pause for Thought campaign. Last year, 756 people contacted the welfare charity within the first three months after Christmas to relinquish their dogs. With over 1,000 abandoned dogs coming through Dogs Trust doors each year, they cannot keep up with the numbers. Their campaign urges people to pause and consider the responsibility dog ownership entails. The charity has dotted oversized pause graffiti across Dublin City Centre and parks like this one in order to get people to think before they adopt. Normally it boils down to the fact that they just haven't got time or they didn't understand the commitment they were taking on. We'll often hear people say, oh, the dog got too big. There's not just saying a dog has gotten too big. A dog that hasn't been trained maybe seemed too big because he's bouncing up and knocking things over or that type of thing. But a well-trained dog, it really doesn't matter what size they are, because they're well trained. They're not going to be doing all the little things they're not supposed to do. Sometimes people bring them back because they just haven't got time for them. Maybe their work shift changed or they've had a break up in their relationship or their accommodation. There's so many different reasons. But a lot of the time it would boil down to just people who didn't understand what they were getting into in the first place. Dogs Trust Ireland has suspended adoption until the 3rd of January. Shauna Cone, DCTV News. Commuters will face travel chaos on Wednesday with the first of five 24-hour rail strikes set to take place. Unions have been looking for a pay rise of 3.75% with management offering a one-year increase of 1.75%. Talks between management and unions at the WRC took place earlier this month but failed to reach an agreement. The breakdown of the talks was very disappointing because we put an awful lot of effort into trying to construct a package that our members would accept. And to spend 12 hours in the WRC to have, as we call it, the road pull from Wonders at the last minute was totally unacceptable. And now that the company of traders is in this fashion it's going to make it actually harder to come to a deal now at this stage. At Conley Station, commuters reacted to the imminent disruptions. I think sometimes you have to stand up for your rights and they have tried everything. I would be a strong trade union supporter. I'll just be using the bus instead. I don't think it will affect me too much. I think it's important for workers to strike if they think it's needed, I guess. It's annoying when it affects public transport because it affects so many different people but if you compare ourselves against Paris they have so many more strikes. Well, I'm not a regular commuter so it wouldn't affect me directly but if I was a regular commuter I wouldn't be too impressed but then at the other side I can understand where they're striking so I could kind of see both sides but if it would affect me getting to work obviously, you know, I wouldn't be too happy. Over 155,000 people a day are expected to be affected by the staffers. Costing the firm 900,000 per day. CEO of Irish Rail Dave Franks warned the workforce of 3,800 that they may scupper their chances of a pay rise if they continue with the rail strike.


Now we start with the next talk. Therefore a warm welcome to Lukas Fulcille He is a developer of a new protocol and What it's about you will hear in the next Talk about the fin year project give him a warm applause So, thank you everybody for coming here, and I'm gonna talk about This project of mine that I started as my master thesis and then Kept working on it's a new transport encryption and well authentication protocol and the emphasis is on the authentication part The first thing that comes to mind is why do we need another protocol? We have so many of them till us works fine for everybody and Everybody will tell you you do not roll out your own crypto For me, it's a journey that started with solar panels goes like everybody would like solar power, so we put put some some panels in our home and Like any hacker would do we started I started to reverse engineering the rest of the triple protocol for the inverter Sended out that through SNMP to make some graph and that's what's it If you've ever Had to work with with protocols like SNP you You might have a to study a bit to to understand what is going on behind the scenes to understand all the protocol works and Well and to make it work and the reason was Also This was not a very long-lived protocol Sorry a long live project goes well mafia something to say in it and It didn't last more than a couple of weeks, but still it got me starting the you got me starting in the protocol study and And I still think that the SNP's history is is a great place to start so Again It mimics the the history of a lot of other protocols first version everything clear text everything Well, it's just welcome to the hacker Second version we had security, but we're not good at it Nobody Don't worry implements it. It's difficult to actually implement it So we go back and forth and we have the v2c with the v2 features and Mission one security, which is basically none until finally we get it right with some encrypted and outdated version we see this all the time in everyday protocols like The usual TCP and TLS, which is future first security letter But you can say well, this is because of legacy this is because the protocols are old the truth is it's that we haven't learned it really well like if you've studied a lot of other protocols like a ctp and dcp which were standardized, I think in 2001 for a ctp in 2006 for dcp You will still see that everybody's clear text and security is completely forgotten That is until some New protocols experimental protocols like quick and minimalty Which were both born I think three years ago something like that Which Well, the main reason for quick is to try and pull TLS and TCP together and and also add some Multiplexing in the streams so you can have multiple streams of data in the same connection basically what What speedy and HTTP do are doing? And Everything runs on top of could run on top of IP but Technically runs on top of UDP to get through firewalls and stuff What does it mean security fee first, sorry features first and security letter It means that the packet looks a lot like this clear text everywhere. We can track connections. We can result connections Maybe even do some passive fingerprints on the options and then finally we have our data and After well in the TLS sections We can also see here that TLS is still in the Mac first and creep later mode The TLS 1.3 will will change that and go and creep first Mac than neck which is Which is thought to be Some somewhat more secure for a lot of reasons. We won't we won't go in it and And this is what I mean when I say security first features later This is the quick protocol and it's our well the first thing we notice is that Google tried to make Everything as optional as possible so you can skip out wall sections like even the connection ID is You can be skipped out because if you have the UDP tunnel use the UDP connection as an identifier but But still The only clear text parts are the The thing that you need to decrypt the packet or the things that are related strictly to the The end shake part of the protocol Well, finally, we have some multi-stream support in the stream ID and an offset which mimics the The offset mimic mimics the sequence numbers in TCP Minimality that I mentioned before looks a lot similar But the packet structure is more fixed and those very easier to parse But still the the overall The overall sections are the same only the clear text only as the part Only as the part that are needed to decrypt the packet and then the packet is the actual data Minimality is still a support for multi-stream if you want to know which are the The RPC part which can be repeated in the the same packet same as streams in quick So for our protocol, I went for something very similar to minimal T with the connection ID Each when you see connection ideas like this Each part of the connection generates the song idea and sends it to the other so there is no clash or synchronization needed Then we have some multiple streams which will be which we will see more in depth later and some some checks on the It's really the same thing as before except maybe for the padding which I put at the beginning to I'll randomize a bit more than the internal structure of the packet to To make more difficult some some traffic analysis or Or rather small attacks There is also the option for vital in me and about that. I don't think quick supports in In quick everything is bite aligned and I'm not sure about minimal T Anyway, the first thing we do when we When we build our our application is to select the stack of protocols that we will use Since today everything runs on the web. You will always start always start with something like this tsp tls HTTP wow for your authentication and finally the application Which is fine. It's it's not the wrong with this It works Until you need to add the things like Chat video audio audio streams that Do not really work that well with reliable connections and you cannot do with the stocks You need to add another stock and manage these Two in your applications Maybe then synchronize the authentication of wow that you do in one stock on the other and things like that it gets even more complicated if you want to do something like multicast and And yeah, if your application has to synchronize all of this stuff everything is pushed on the all the complexity is pushed on the application and We can really expect the normal application developers to get this right every time so big frameworks and Another stuff everywhere What we want to do instead is probably move the the management of all of these stacks inside Inside the streams that were before but in it's something that That both quick and minimally missed because they stick to TCP like connections There is some some way to do UDP like connections for Streams in quick, but it's more of a hack than than the way the protocol is used thought and And still none of those protocols as least at least as far as I know support multicast So In Farir We have an explicit creation of the streams Even during the end shake so you don't have to waste it more round trips and We can have any combination of reliable and reliable order than order a datastream or datagram basically any any Any that you can think of if there's some that are quite difficult to manage them Something that quick introduced in protocols, but was already done in In other parts, so it's not really a complete innovation is the forwarder correction of packets We can introduce something like right for for the network where every two packets that you send you send Exhaust of the two packets so you can lose one of the two packets and Still get your data I Developed and you can you can use out the Libre uptor queue which implements the Raptor queue algorithm and it's actually generalization of this linear combination of Pockets so that we can generalize on any number of packets from the source and any number of repair packets so So you can actually tailor your error correction depending on on your network properties Finally multicast support Multicast is needs to be treated a little bit different though because For example, we have support for multicast even in the DTLS Specification that is in an RFC, but what it does is basically just Share the same key with everybody which works is fine, but then every client can impersonate the server With the sending data to other clients pretending to be the server simply because well, it's the same key so to fix this in Farrier we simply reserve a connection ID and the identifier for the multicast connection is actually the the public key which is We use elliptic over elliptic or the cryptography through a lip sodium And then we sing The the packet with the with the public key directly elliptic with cryptography is fast enough for this We It was something not really possible with RSA, which which is somewhat slower The the last thing about managing entity everything in the same protocol is that we can also associate that The multicast connection is actually associated with the unicast with one or more unicast connections And it means that we can use the multicast connection to just send the data to the clients And then use the unicast connection to send more recovered data or the packets that were lost And we can have something akin to reliable multicast, which is nice still We we were talking about the application stuff the the application stuck let's look into it a bit deeper and compare it to the the osu! layers and the osu! layer pilot the doubt stuff like authentication encryption is not Is not included because you can do it at multiple levels But we can see some interesting stuff like TCP and TLS And HTTP well are both transport protocols, but while TCP and TLS have their own sessions Which are different because the TLS sessions need to be cryptographically Cryptographically verified and everything HTTP does not support sessions so you actually need to reintroduce the session in with the cookies and And also you have a different session for the authentication in OU Which need to be synchronized in with the cookies and and this is what we mean with I meant before what the The complexity is pushed to the application because now you have to synchronize things like the OU the cookies manage the The session that you that HTTP took away and stuff like this We have also multiple ways of multiple points where we do the authentication or we cannot really fix the The session part is because simply HTTP took it away We can do something for for the authentication so What are the authentication models possible the most simple one is the client server that is used in TLS and well and And what what your application can easily implement? You have the Federated model like Kerberos and Wow, which we which is somewhat of a match between the client server and the federated because it should be it looks a lot like the federated model but then you don't have an automatic discovery and things are Things are difficult to implement and And anyway, all of these models have the real problems like the client server model Only it can give you too many user and passwords, which is our current problem or Or you can use a certificate with and then you need to to think about renewal revocation issues and stuff The Kerberos federated model is actually a very good one But it requires clocks synchronization, which is very difficult for embed the stuff like the badge, which is What update failed nice Like this badge, which does not have a clock inside and still requiring clock synchronization on the internet there is something that you probably don't want to do and Finally, well, it's just a big back of nope if you follow the development of this protocol you will already know that there are some stuff like the The main auto row 4 to 1 which worked, you know how to and got away a couple of months before the standardization of this protocol asking for a same to be taken out of the all the documents inside It was they tried to standardize this as a protocol, but it's all loosely defined that They couldn't do it. And so it's actually just a framework and And And it works. I mean, it's it's safe everybody use it because cryptographers and security people have gotten together and Now the libraries that you find on the internet are actually a very specific subset of wow because if you you can actually have implementations of wow That that are completely Conformant to the specific to the specification, but also completely insecure. So do not implement or out What I chosen for this project is the federation model and I actually try to separate the Various Missing the words the various Parts of of this all of this federation. So you have your application like your web browser the client manager, which is something that I don't know like in the Kerberos model that the application that manages all your tokens and Authentications, then you have your server service, which can be the The web server and Finally the the authentication server, which is a separate entity from from the service And Overview can be something like this where the application connects to the manager local in the same machine The manager does all the handshake and authentication and token management stuff With the authentication server, which then just Notifies its service because the service since it's inside the same domain That the authentication server manages About well, it notifies it about the new user it sends back their keys and connection information like connection identifiers and other stuff Which are sent back all the way to the application and now the application can connect to the service directly Without any more handshakes or round trips and stuff This is actually one of the few models that you can have without the clock synchronization And yeah, I think it's it's good enough and also as I said formally verified that through mathematical properties This the previous slides left a big hole However, what is the trust model of the of the whole system? I mean we can do we could just use the certificate model Which has a lot of different problems as we know it or we could just you could just use DNS SAC which is almost available for for any TLD domain now and So that's what we do we We create a binary with With information like multiple authentication service IP is UDP ports to connect to multiple public keys so that so that you can do roll out of new keys very Very seamless and Worsting support is is to do We don't use the X 509 Certificates just playing keys Because well X 500 and is a very complex and Very abused the standard. I think the implementation in new TLS is like 35,000 lines of code just for parsing the certificates, which is I've been too much and Also, we don't strictly standardize on a single trust mode. So you can extend it and it's all managed via plugins if you want to If in the future we want to add something like GPG we we could TLD just like the the tour guides do and and get info from the Web browser and save our Our binary encoded inside some description field So it's it's very easy to extend Also Z 85 was chosen for the encoded because it's somewhat more Efficient than base 85 and it's actually a steering safe We were talking about Authentication authentication is handled directly in the end shake Which are designed to To avoid completely any kind of amplification attacks Which also means that we cannot have zero round trip connections like Like what minimal T and quick actually do It's a design choice mainly because This way we avoid any problems with the roaming stations and such There are three different end shakes which are taken roughly from TLS Which is well, which requires three round trips then we have a stateful connection which requires a bit of a state in the In the first round trip It has a it also has a weaker form of perfect forward secrecy Which means that basically you don't have you don't have a One key one ephemeral key generated by the server for every connection But just one key shared with every connection for like five minutes Then you drop it and generate a new one and go on like this it still works both quick and minimal T do it like this and After it's not as safe and as well as as robust as the as the as having a perfect forward secrecy per connection Then finally we have a one round trip way to do the connection which however needs to Synchronize the the keys with the DNSSEC so you continuously roll out new keys and this is the way you do perfect for what secrecy Again, this is formally verified through proverive models You can have a look at them. It's all it's all on the web and And the auto-addiction is actually token based as we said before which makes it very easy to To manage and tokens are actually just random strings of Like 206 and 56 256 bits So there is no senior require for tokens Which is something nice that comes from taking out the The clock requirements the crocs in chronic synchronization requirements so Another thing that we we use inside the the authentication is authorization which is it's not something that well to introduce but It's something that to out uses Very thoroughly actually out as another nice thing that is an application authentication where you put the But the identification and of this application and your password inside the binary which that everybody can get so But the actual authorization part is the scope so when you When you develop the application you see in the documentation stuff like using user read the file right To limit what the application can do we have the same thing in ferry but we We put it in a lattice to To put the numerator easily numerator and And walk through this. So well, we still have our device identification not an application identification Like wow giving a hierarchy scope to To the authorization allows us to tie a single token to an authorization and do fun stuff like Limiting the the token authorization without Regenerating the token at multiple points so we can limit the authorization at both the authentication server because every authentication works right through there and At the client manager point This means a couple of different things first that application absolutely do not manage anything related to tokens and shakes authorizations nothing like that. They only get the keys and the and the IP address is to directly connect to to the service The the lattice needs to be synchronized between servers between service authentication server and client This is because the user so that the user in the can actually select and limit the for example an application that you're testing to a specific scope and The limit is Enforced by the protocol itself. It's not a self limit from the from the application so even when you're testing a third-party application this way you can be even more Safe on the on the application limit There is some hardening inside all of this All of these key exchange and generation of tokens so for example There are a share of secrets between the client manager and the authentication server and service Which enable which are basically just strings that absorb the with the tokens And I am actually experimenting also with something like hashed OTP is so so that you can actually check how many times A token has been used in the in the service and avoid things like Token stealing and being immediately notified about that Still just a couple of these things of these things like putting another public key in the trust service enable us to completely Take away that The nice single point of failure that is the authentication server that That would usually be the the first thing an hacker would target, right? It manages all the authentication is as it has all the tokens, but even if but now thanks to some Some just soaring of share secrets Even if you hack into an authentication server All you will manage to do is to force the the Austin of the authentic at the the C sub mean of the authentication server to just regenerate the share secrets which Which will also as a nice side effect that every client will be immediately notified of a breach of Things like the service or the authentication server. So So we will be able to To me immediately know something like that and it will also have seen in disclosure In this yeah in in disclosing this this type of breaches The end result of all of this again is a formally verified Secure transport where all kind of transport are included and easily ask accessible to the To the end user The since every token is managed again by the client service the user only has to decide whether to allow an application to To access what it has to access or not Application and services never see again authentication data So we have less and less Security related stuff inside the the applications, which is a nice thing We have a forced maximum authorization and yeah the It's no longer a single point of failure. So what's the status of all of this Libra Torque you the forward error correction? Implementation of Raptor Q Works I Need a couple of approvals to roll out the new stable release Everything is LG PL 3 Ferry The library implementing it is still not finished Currently and shake works the trust model works The connection is set up, but we need to finish the I need to finish the control flow, which is a big part of having a connection But still everything is managed through a plugin architecture Which is very thorough. So she can actually add and delete stuff as you want and experiment with everything and That's it everything is on the website and please have a look at it and And any any questions? Yeah, thanks a lot. If there are any questions, please go to the microphones in Front or at the end. I don't know if I can express this well, but I wonder About using it with an RPC protocol. Can you can you speak about bit list? I wonder about using it with an RPC protocol where there is a request and a response and They may be overlapping On one of your slides you said it can be like data grammar data stream ordered or unordered reliable or unreliable Reliable If a request is a datagram it might be bigger than a packet though But it does not need to be ordered. For example, you could send out three requests and then get the replies in a different order Yeah, yeah problem over TCP because you have the headline blocking and yeah So you accommodate this and do you have some RPC framework that you suggest using with this so the application could actually I I've not gotten through something like the developing an RPC protocol Taylor to this But yeah, you can you can actually choose per stream a combination of one of the the three of the three features and Just use it you can actually have also big messages in In a data in a datagram fashion because the the message is split between multiple Multiple packets, so you're not limited to the to the sides of a packet for your datagram messages And if you lost one packet it would retransmit one packet not the whole datagram. Yeah, that's yeah, that depends on the Well on what you choose for error correction and whether you have a data gram Which is what which was unreliable or reliable? Yeah, any further questions? No, then thanks once again to Luca and the one well


Hey guys, welcome to Rotorite. Today we're looking at a revolutionary new FPV system. This is coming out from DJI. They're coming out with an FPV system that's all about HD. And they have put together the whole kit for you, which are going to be the DJI goggles, controller, and also the DJI air unit, which is going to include this box here, the camera, and the two antennas. This is going to actually record HD footage on board with an SD card. So you're going to get 1080, 60 frames just out of this. So depending on we'll see how much we will like the quality of it, but it could possibly replace your GoPro. It's going to be kind of hard to fit on different frames. It's a little large, but I mean, it's really not too crazy. We're able to fit it in this teeny race drone. And this handles radio signals and the FPV video all in one unit. The DJI is full HD in the goggles. So not only are you seeing exactly what you're recording, but it makes the experience that much better. That's crazy. That is nice. That's kind of nice. Condenize. That's kind of sharp. That's kind of sharp. That's like 4K. Yeah, that's a really high quality image. I'm done with it. So does it stay really solid? We're about to find out. Like there's no kind of click of nothing? Does it look like that all the time? OK, where's the arm then? What's so special about this? There's been other HD systems before. Special about this one is the latency. They're boasting about a 7 to 28 millisecond latency. And what I see that as being is from your control stick to when your drone actually makes that maneuver, is about 7 milliseconds. And then from you touching your controller to what you actually see in your goggles is going to be about 28 milliseconds. If you compare that to other things that we have on the market, I mean, we're probably used to flying with about 30, maybe 40 milliseconds. I mean, I'm not sure of the exact number, but the point is 23 is really fast. I took it, not even seeing any of the specs beforehand, and I went out and flew. And I mean, I didn't notice any latency at all. Yeah, I can get used to this. Does it stay crispy the whole time? Oh my god, it's not a bit of static. And I'm like all the way at the end. This is the future, bro. It's not even the future, it's here. It's right now. This is the present. It's a crazy time to be with it. Does it feel like any lag in the latency? Not enough that I would be like, oh, it's too much latency. I'll take this all day. This is what we need. Like it literally looks like I'm watching the Discovery Channel.  I'm like, no, man, it kind of looks like reality. It's just beautiful. It's even sharper than a GoPro. Bro, it's, it's, it's, it's, I haven't seen a bit of static. This is amazing. Like this is everything that FPV was missing, that right there. I mean, I went all the way to that white sign down there, not a bit, not even a twinkle of breakup, which so ever. And that was everything, everything you guys just saw. That was all like DVR from the goggles. We don't have an SD card in that yet. Let me put an SD card in the quad. Ah, yeah, that's nice. Yeah, what can I say? That's amazing. Oh God, that is really good. The quad doesn't fly amazing. I wish we could fix that, but wow, it's good. No breakup, right? No breakup. It's just a shaky quad. Just pretty sure we, I can go over here. Yeah, I'm completely behind the building, like no line of sight at all, worst case scenario. Has no like latency in that. It's getting just now, it's maybe getting a little more latency, it just now started to pixelate. And I'm like, I would never be able to go here on regular gear. But like look in the lower corner, it tells you the latency, what does it say? 24 milliseconds. No, that can't be right. No, it's just 35. Okay, that sounds maybe more right. Where are you at? You're not behind the building. I'm like right in the middle of the courtyard. Like I'm about to do like the thing you would always say, like I wish you could do that, just go all the way around. It's getting really pixelated now, but pixelated is like rough video. It's failsafe now, but I'm in such like, okay, I'm just gonna disarm it. Did you failsafe it? Yeah. But I'm in like, you would never ever do that. Like I'm totally in the center of the whole thing. That's an important thing is how is the, the failure going to be, because analog, we're really used to flying analog, where you get snow. You get kind of snowy.  You know when the video is getting worse and you can fly through it. You get used to like. Yeah. I think that was the downs, like the downfall of the pro site. Of the other, yeah, other HD systems that have been out before, they don't get snowy or a little get a break up. They freeze frame or do something really bad.  Yeah, big problem with that. So this seems, it gives you a good warning. You'll know when it's going away. That's, oh come on. I keep flipping it. There we go.  There's lots of dew back here. I feel like there is a little bit of latency. I'm kind of struggling. Maybe a little bit. But is it worth it? You know what I mean? Absolutely. It's almost like worth the latency. Oh, there it is. There it is. There it is. This problem. It's really good. I just want to play with that all day really. It's all I want to do. You know something that I do think we were experiencing was feel, it's not too bad now. This unit gets really, really hot. I believe that when that's getting hot, you get more latency. It kind of goes into like a lower power mode, you know? So I think maybe that was it.  The system's not perfect. There are some things I'd like to see improved. I really want to see the air unit get even smaller. I feel spoiled because this is the smallest HD unit to ever exist. And already I'm like, we'll only make it smaller but you know, we're just used to much smaller components. But you know, I think we might see frame makers start coming out with specially designed areas to put this thing because it's totally manageable. It is just a little bit larger than what we're used to. The goggles, they're not as comfortable as what I'm used to. And we got some light leaks. See how I'm like, get my fingers in here? I'm seeing reflections on the screen. These look like you're the bad guy in some sort of like alien flick. I'm curious to see how the fit is and you know, if you have any light leak issues because I get a little bit. There is a lot of light leak. Can we make this tighter? Oh no, that's way worse. Oh worse. Yeah, take the head down. First thing I'm gonna say, I have a pretty small narrow face and there is like, I can see the trees and the reflection behind me over here.   Let's get them in the air. We'll see how they video. So I'm kind of scared because you said something about latency. Well, that's just the thing that's been the problem with HD but are you experiencing any latency? Definitely doesn't seem that way. I mean, this is unreal. The goggles, I kind of hate but the video itself is amazing. Can you use this video system with your own goggles? No. You have to use that. You have to use the goggles. That would be the killer for me because if I could use- Your fat sharks, right? Or if they were comfortable and fit similarly. Like I said, it's just, these are really flat. There's a lot of light but I'm not noticing any lag at all. Do you see the recording icons on the screen? I do. Yeah, I forgot to hit record but luckily it came set up that it starts recording when you take off both the DVR and the goggles which is a 720p DVR recording and the onboard unit which is going to give us a 1080p 60 frames a second. So you don't have to carry a GoPro? You do not have to carry a camera.  If you want to go like 4K or something because that maxes out at 1080 right now. Yeah, but most people are fine with that. I'm going to see if with the hoodie I have less light leak because there's a lot to have the straps up and then have a cape. And now I really do look like that. And now you look like Star Wars. Ta-da! So we're going to set up to do a bit of a range test. We're going to find a long stretch of pretty remote road and we're going to set up the pilot on one end going to fly a straight line chasing a car. In the car we'll have multiple spotters. One of them will even be on the phone with the pilot. We're just going to fly it until either the video cuts out or until the control link is lost. The DJI claims that these things can go 4 kilometers out now. I'm actually a bit skeptical about that mainly because our FBB systems that we currently use on 5.8 gigahertz, 2.4 and 900. Even though sometimes you can get that much range generally speaking in the environments that we fly it's almost impossible to get those results. So we're going to see if what DJI claims is actually true. I'd like it to be able to go 4 kilometers out. That being said, I'm not sure. I really don't think that's going to happen. We're actually going to stay pretty close to the ground like we would normally in a racing or freestyle situation as opposed to those long range systems that you know work. You're typically up and out away from your body and have clear signal. We're going to go just like we would if we were flying for real. So that'll definitely affect the range. It's going to be more real life for us. We're not going to typically be in those situations where we have wide open nothingness blocking us. We're going to have obstacles. So we want to see if this is going to be a system that'll work well for FPV. Do we have communication with the pilot in command? Yes, sir, brother. And I am beginning to drive. And it's sweet. He's right on us. Oh, yeah. I see him right in the rear view. Hi, Alex. I'm in front of the car. Hi. Oh, God. I have the signal. Pretty good. Pretty good.  I'm going to hit you. Keeping visual contact with Yandrone. I could just reach out and grab that thing. I missed that little high sign. I get splashes of water. Oh, yeah. Watch out for splashes. It's so close. How does the water look? Oh, man. That means it's going to go down in water potentially. OK, wait. No, we're going to be clear of puddles in a minute. I'm going to go ahead of you. OK. We got a line of sight. We got you. It's starting to get a little slippery. Yeah, well, the car is between you. So maybe stay just behind the car so that we're not blocking you. OK, we're clear of puddles. So if you're going to go down, you should be pretty safe to go down. But I wouldn't maybe necessarily be so close to Jamie when you're going to go down. Oh, she's fine. We are pretty far. We're at an intersection. It's really good. Like, the signals are great. We are coming up to an intersection. So I'm going nice and slow. There's people. Hey, everybody. Like, what the hell? Dude, it feels so good. That was hilarious. Is it good? Oh, peace sign. We've gone up. We've gone over a little bit of a hump. Now it's getting flaky. Now it's getting flaky. Is it? All right. It's getting. It's going to go up. Hold on. I'm going to pause here. Just hover behind us. Hover behind us. I'm going to let a car pass us. Get behind us. There's a car coming up. OK, we're clear. Get back in front. There we go.  So what do you see? It's better now. It was bad. Now it's better. It's not where it was, but it's definitely more than flyable. We are so far. Oh my gosh. How far are we, you think? I have no clue. But you're really close to the car. Oh my gosh. Is that shot sick, Jamie? I'm glad the image just got clear.  Sorry, Jamie, didn't mean to get that close. We're going under some power lines, so be careful. I guess you can because it's A-D. Dude, it's so clear right now. I don't get it. And the control. Here's another thing. The control feels really good, too. It doesn't feel like the latency is increased or anything. Does it feel like there's any latency or anything? No, it feels the same as why it took off. Wow. Dude, it's pretty clear. I can see you really well, your eyeliner and everything. Watch out, Jamie. Oh my gosh. I see. I see. Blah, blah, blah, blah, blah, blah. No, I just can't imagine that happening. Don't worry. Don't get between the truck, man. It's going to block you. I can't believe how far we're driving. It's so far. Dude, it's so good. OK, now it's getting a little bit more flaky. OK. But it's good. Like, it's flyable. Now it's getting, now it's the worst it's been, but it's back to it. No, it's OK. It's weird. Now it's coming in and out. All right, it's going to go soon. It's going to go. Is it going to go? Nope, it's good. What? No, dude, it's so like, it'll go, it'll just be like normal static. Why? It's going to look different. Like right now it's really hard to, like, I'm not going to get close to the car now. It's too rainy. OK. So what do you see? But now it's better. It's probably not flyable. I'm just kind of holding the stick. OK, Jamie, come in the car. Come in the car. Oh, he hit the car. He hit the car. All right, we'll call it there. Oh, OK. He hit the car. So that is, we made it 2.39 kilometers. But that's like low to the ground, too. Like, that's not high up. Yeah, I know. We had a lot of. 1.48 miles. Basically a mile and a half. We made it a mile and a half. I'd say that's, I'm impressed. I'm impressed. Do you think that the battery had anything to do with him losing video? Because if he was in the air for like six minutes. I don't think so. He said he was still at like high 15s. So, um. He was 15s, but. He just got to the point where I couldn't, like, fly it anymore. So I just, like, ditched it. That's nuts. OK, we'll come back. That was insane. That was nuts. I was freaking, you got like halfway there. And the first time I said I think it was going to go out, that was the first time I experienced static. Yeah. Or what, like, static looks like. But immediately it just came right back and it was perfectly clear, just like I was here. Towards the end, it just got really, really bad. I'm like, OK, should I put it down? And I'm like, OK, I'm going to put it down. But like, I didn't know how to put it down. So I just disarmed. That's fine. You did hit the truck. That's OK. Yeah. Better than any. I thought I did it. You were so close. How close was I? Like, put your hand right where I was. Like, no joke. Let's all talk about how good Alex is. I know. Let's do it. Let's walk through the user interface of each of the items that make up the DJI system. So starting with the Air Unit, which is the camera, as well as this box that handles the video transmitter capability and the receiver capability of the system, there's not a lot that you actually interface with. There's a slot for a microSD card so that you can get onboard recording in 1080p and ports to plug in your two antennas and your wiring harness and a USB port for updating and things like that. So setting this guy up to your flight controller will actually be pretty easy. There's just going to be two power wires to power the unit. And you can just solder those directly to wherever you're getting your main power from. This will be able to take up to 17 volts or up to a fully charged 4S LiPo. And so after the power, you're going to have three wires left that you have to solder up to the flight controller. And that's going to be your control link wire. Like, you would put it to like an S-Bus pad. And then you're going to have a TX and RX for your communication to get the information from Betaflight. And that was one of my biggest surprises because like I said, DJI is not really known for integrating with other companies or other products. So that's really cool that you can actually get the Betaflight through the DJI system. The radio is going to be very much what you're familiar with if you already fly drones. Very similar if you've ever seen like a DJI Phantom. It's really similar to controllers of that. The gimbals feel good. It's a little bit smaller than like a Taranis FR Sky radio. The sticks are a little closer together. But when I was flying it, that wasn't an issue for me. They've actually let this be integrated into Betaflight. So you can assign these switches to whatever channels you need to. It's not just automatically preset. The only thing that you can't configure is the start and stop recording button. But other than that, it's just like any radio. It's really weird to see something that looks like a DJI controller but functions like a FreeSky radio, right? Very similar stuff that you may have seen on a DJI controller before. You got your power button. Four switches on it. There's a button here so that you could remotely start your recording on board the drone. That's pretty awesome. And you're gonna see there's two antennas. The one controller and error unit is controlling both of your video and your control link. So this is your battery compartment right here. I'm assuming you pull that down. Boom, battery. Looks like it's got a USB3 on there so you could charge it that way. That's the controller. There's not a whole lot to it. It's pretty simple. Yeah, I wouldn't mind if this was my controller for how good the video is on this thing. The goggles are what's going to provide the most unique part of the user experience for this system. To power them up, you have a harness that you can plug in any lipo up to 4S. You also have a headphone plug so you can get audio out. And on the other side, you've got your slot for your micro SD cards that you can record the DVR of the goggles and you've got a USB plug. On the bottom, you've got sliders that you can adjust the IPD. That's the interpupillary distance to adjust for the spacing between your eyes. And as far as buttons go, over here, you've got a five-way joystick type button that goes up, down, left, right and pushes in. And that's how you navigate most of the menus. Right next to it, you have a back button so you can back out of the menus. And right next to that, you have a start and stop record button. The only other buttons on the other side are quick access for changing channels. We'll show you a little bit about how that works. So in the goggles, you use your joystick button to open up the menu. And entering the player menu allows you to select a channel for your drone. You can move to a different channel. And the cool thing is that because the air unit and the goggles are paired, when you change your channel, it changes it on both units. There's no more trying to remember what channel you're on or anything like that. When you set the goggles to channel three, the air unit instantly goes to channel three as well. In fact, it's kind of weird because when you change channels, you don't even lose video for a second. It's like a very seamless change. So that's pretty cool. This audience menu, that'll be used in our other set of goggles in a second. I'll show you how the spectator function works. In playback, you can look at all the DVR footage so you can play back the recordings of the goggle video itself. And then down in settings, there's all sorts of things that you can change. You can change your camera settings, including aspect ratio, your color setting scene, saturation, white balance, all sorts of stuff. There's settings for your display. You can zoom in and out of it, which effectively resizes the display. So if you think that the field of view is too wide, you can kind of make the field of view smaller by zooming out of it. I thought that was really cool. You have settings for recording. You can change between 1080p, 60 frames a second and 720p and 120 frames per second. So you can get a little bit of slow-mo there. Here where it says PID tuning, this actually accesses the PID settings of your flight controller if you have the air unit hooked up to it properly. So you can change your Betaflight PIDs right in the goggles, which is just awesome. The fact that DJI is interacting with Betaflight in this way, super exciting. Very intuitive and straightforward to use. The joystick just feels very natural to navigate everything. And over on the other side, I mentioned these buttons for quickly changing channels. So if you don't want to go into the menu to change your channel, you can do it right here with this up and down button. And you have a cool readout that shows you what channel you're on. So if you're changing your channel from outside the goggle or if someone wants to see what channel you're on while you're flying, shows it right there. So the other thing I want to show you is if you have a second set of goggles that isn't paired to the air unit, you can use these in audience mode. You can go into the menu and access audience mode. And that's gonna then show you channels that are being transmitted on and you can tune into that channel and you can watch other people flying in your goggles. So I'm really glad that we have two sets of goggles because now using the second set, we're gonna be able to use the audience mode and show you guys exactly what FPV in these goggles looks like. Both in it. So Alex should be able to watch me flying out. That sounded interesting. Yeah, this thing, I don't have it tuned all that well. So I'm going behind some trees. It's so much fun to like just fly though. It's kind of a whole new FPV experience. It's definitely not a finalized product. I like it a lot. It's just, it's so clear. You're doing a good job flying right now. Thanks, Alex. They say that the audience member will have a little bit more latency and a lower quality and less range. So. Now why is that? Is it linking to your goggles? It's because the, I hope I'm explaining this right. If I'm not explaining this exactly right, apologies. But my understanding is that the radio link and the video signal, it's all one communication. So it's all one feed that's like put together if that makes sense. You're only picking up a part of that feed rather than the entire package, which I guess reduces the performance. That's my understanding from what they are essentially permitted to explain to me. The whole system is a 5.8 system and it's all together. It's RC and video on one 5.8 situation. If that makes sense. That makes sense a little bit. In your opinion, would you still want to run a GoPro on top of this? I, you know what? We'll have to check the footage, but I probably would because this maxes out at 1080 and I like to film at a higher resolution. It's also 4.3. And this is, you can, this is recording right now in 4.3. You can switch it to 16 by nine, but what it does is it crops the top and the bottom of the image and it does it while you're flying too. So what I'm doing is we're filming all this in 4.3 and then my plan is in post. Oh boy. Mine just froze. Whoa. Mine froze too. Mine totally froze. Mine froze completely. Oh no. Yeah. It just went total locked. That's exactly what we've talked about a few times about. It was previous HD systems. That is. Scary. That's the worst thing that can happen. That was very scary. It was not predicted either. It wasn't like it was starting to go out. It just locked. In all the flights, I haven't had anything yet. So that's why I've been so impressed with the system is because I've done 10 flights and I've never seen anything like that happen. You almost landed in an empire. You know what? Oh no. There may have been a reason for it doing that. Yeah. That's not related to the system. The ESC caught on fire. Who built that one?  I built it. Do you not know how to solder?  By the place of my honest prediction, I'd probably say your solder fail meter, but it doesn't really make sense. No, I think the ESC failed. We were getting those jitters. Yeah, it's true. It might have been about ESC the whole time. So I think the ESC smoked up in the air. I can't really fault the DJI system because it has been working great. We flew it super long range even when it would kind of go not to static but to its type of like pixelation. It never once froze up on me. So I'm going to give it benefit of the doubt but I'm going to proceed with caution. I'm jazzed. Are you jazzed? Woo! I think this is kind of the first step into the future of FPV. I think it's a big leap. Yeah. We haven't had as many big leaps in the hobby lately. I feel like the tech is kind of plateaued. This is a big jump. Right. It doesn't make the entire FPV experience foolproof. We still did have a failure, which we determined was an ESC failure. So the ESC failed in the air. I wouldn't blame the DJI system. I don't think there's anything. I mean, anything's possible. That being said, it did survive the fire. We got the scorch marks to prove it. So DJI can totally advertise that this is fireproof. Pretty good. It's pretty damn good. So it's not perfect. I think the biggest problem we all faced was the fitment of the goggles. Yeah. Right. We all had some light leak issues, especially Jamie who has probably the smallest head. DJI has told me that they are going to be coming out with different foams. So this just Velcros onto the goggle. You can put different pads on here and they're going to be coming out with thicker versions to make up for different styles of faces, I guess. But to their credit, that's the only downside I can see to it. Right. Well, the size too. I mean, I was expecting bigger. This is as small as an HD system has ever been for sure, but it's still not going to fit in most of the frames that are out there. As far as dimensions goes, it is 15 millimeters thick. It's 45 millimeters long and about 40 millimeters wide. So it's pretty, it's pretty large. It's not, but it is as small as HD video has ever been. So I don't know if I'm going to convert all of my quads, but I'm going to have a quad with this for sure. We should talk about the price. We have not in this whole video yet mentioned what any of this is going to cost. Yes. It's not going to be cheap, is to be expected. Any DJI products, not really the most budget friendly thing, but it's not astronomical either. Okay, so let's start with the radio. What's the radio cost? Radio is 300 bucks. That's pretty good for radio. There are cheaper radios out there. It's a little pricey. There's definitely cheaper radios. There's definitely more expensive radios. I think the downside is it's $300 for radio that's only compatible with this air unit. And you can link multiple air units so you can get the radio and get multiple air units. So just like we have one radio that we fly all of our quads on, you'll have one radio that you can fly all of your DJI FPV quads on. Yeah, so if someone's just getting into FPV and this is the route they go, then that makes sense. They're just all in. They'll just only get this unit for every quad they build. They'll use that radio. And you know, if you are already into this and maybe you don't want to buy all this stuff all at once, you can skip the radio. You can wire in your own receiver and just use the air unit for video. So even though the air unit is always going to be capable of both video and the RC link, if you don't want to save 300 bucks, you don't need the radio. You can use your own receiver and radio system. But there's another component that you're gonna have to fit in there when this is already pretty large. This is true. All right, what about the goggles? How much are? The goggles are $529. That's pretty good. That's not that bad. That's less than- Is that less than- The Shark HDOs with any, you know, pretty much any receiver that you could, I don't think there's a $30 receiver. Yeah. So for, it's definitely a higher resolution screen in them. If these goggles could be compatible with analog video, they would be a total winner. I would say just get these because why not the downside is they are not compatible with analog video. So it's only gonna work with the air unit and these you are going to have to use. There is not currently a solution to get video from the DJI air unit into any other display. Not gonna work. So you have to have the goggles. But $529, that's really not that bad. I expected them to be like $6 to $7. I thought this would be like a thousand. They look like they're worth a thousand. They're very fancy looking. The actual air unit, the thing that you actually fly with, what's this? That's $179. Can you get the components separately though? Like, cause what if I smash- Oh yeah. So if you smash the camera, that's $59 to replace. Dude, that's not bad. It's not that crazy. That's not that bad because I think- And the FPV cameras are around 40 that we use right now. Oh, that's not that bad. Another 20 bucks. And then if something were to happen to the air unit, that's $100. All right, so let's say I'm sold on this. I want the goggles. I want the radio. I want the air unit. What's a whole system? What's that get up to? It's gonna be $929. It's a lot of money. It's a lot of money. It's definitely a lot of money. Right. I would say it's worth it. But again, like with other systems, you get the radio, you get the goggles. Those are the big investments. You can start buying multiple air units and move your fleet over. It's gonna sting a little bit for people who have already spent 500 bucks on goggles and a couple other hundred bucks on a radio. I know there's someone that's like, ah, I just bought HTLs yesterday. Yeah, that's gonna be fun. That always happens. The minute you buy a new iPhone, the next one comes out. But I think it's fairly priced. I do too. I would say it's overpriced because this is an experience you're just, it doesn't matter how much you throw any other directions, you're not gonna get it. It is, it's a special experience. I'm pretty into it. So I will be flying one of these. Like I said, I don't know if I'm gonna be converting my entire fleet just yet, but I like it. I know, I'm kind of thinking just, I gotta go. No, that one's mine. This is mine, I'm not. All right guys, if you have any questions about this system, leave a comment down below.
