- A satellite is an artificial object that is deliberately sent into orbit in space, usually in order to send, receive or bounce back information to different areas of Earth. Artificial satellites are man-made satellites, they differ to natural satellites such as the Moon which orbits Earth and Earth itself which orbits the Sun.

List of satellites in geosynchronous orbit A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit at zero inclination (that is, directly above the equator).A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit at zero inclination (that is, directly above the equator).

- Science background Information: A satellite is an object that revolves around another object in a path called an orbit. Satellites can be either natural or artificial (man-made). Our moon is an example of a natural satellite as are all the moons of the other planets.The earth can also be considered a satellite of the sun.cience background Information: A satellite is an object that revolves around another object in a path called an orbit.

- Geostationary Satellites. There are 2 kinds of manmade satellites in the heavens above: One kind of satellite ORBITS the earth once or twice a day, and the other kind is called a communications satellite and it is PARKED in a STATIONARY position 22,300 miles (35,900 km) above the equator of the STATIONARY earth.

- The global positioning system (GPS) is a series of satellites in orbit around the earth, that can talk to any GPS receiver on the ground, and that receiver will show it's lo … cation on earth to withing about 20-30 feet in any direction.ll the satellites transmit the signals down to Earth in the global positioning system. Each satellite is programmed to send the signals at the same time. The signal contains the digital information about the satellite's identification and position.

communications satellite Often abbreviated as comsat, a communications satellite is a satellite that has been stationed in space for the purpose of providing telecommunications. Communications satellites are commonly used for mobile phone signals, weather tracking, or broadcasting television programs.

How Satellites Work A satellite is any object that moves in a curved path around a planet. The moon is Earth's original, natural satellite, and there are many man-made (artificial) satellites, usually closer to Earth. The path a satellite follows is an orbit, which sometimes takes the shape of a circle.To understand why satellites move this way, we must revisit our friend Newton.Newton proposed that a force -- gravity -- exists between any two objects in the universe.he path a satellite follows is an orbit, which sometimes takes the shape of a circle.

What Is a Satellite? This article is part of the NASA Knows! (Grades 5-8) series. A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word satellite refers to a machine that is launched into space and moves around Earth or another body in space.

GPS navigation device The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense.

- The Global Positioning System is a series (or “constellation”) of satellites circling the Earth, each broadcasting a unique signal. These signals, usually three or more, are detected by electronic units, and, thru triangulation and time delay sensings, provide an extremely accurate location readout of the GPS receiver. Many balloon pilots carry a small GPS unit on board the balloon to determine location, ground track and ground speed.

Satellite Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit.

Satellite The first satellite, Sputnik 1, was put into orbit around Earth and was therefore in geocentric orbit. By far this is the most common type of orbit with approximately 2,465 artificial satellites orbiting the Earth. Geocentric orbits may be further classified by their altitude, inclination and eccentricity.

Satellite navigation A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows small electronic receivers to determine their location (longitude, latitude, and altitude/elevation) to high precision (within a few metres) using time signals transmitted along a line of sight by radio from satellites.

- The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense.GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. Each satellite is built to last about 10 years. 2  Replacements are constantly being built and launched into orbit. 3  A GPS satellite weighs approximately 2,000 pounds and is about 17 feet across with the solar panels extended. 4  Transmitter power is only 50 Watts or less.

Global Positioning System The Global Positioning System (GPS), also known as Navstar, is a global navigation satellite system (GNSS) that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

What Is a Satellite? As more satellites are launched the chances of a crash increases, in 2009, two communications satellites - one American and one Russian - collided in space. Space probes have been put into orbit around other planets and moons in our solar system.

For example, the Global Positioning System constellation consists of 24 satellites distributed in six orbital planes with similar eccentricities, altitudes, and inclinations.

List of satellites in geosynchronous orbit A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit at zero inclination (that is, directly above the equator). A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term geosynchronous may be used to mean geostationary.

Natural satellite Nineteen natural satellites are large enough to be round, and one, Saturn's moon, Titan, has a substantial atmosphere. A natural satellite or moon is a astronomical object that orbits a planet or minor planet. In the Solar System there are 173 known natural satellites which orbit within 6 planetary satellite systems. In addition, several other objects are known to have satellites, including three IAU-listed dwarf planets: Pluto, Haumea, and Eris.

Natural satellite Most of the 178 known natural satellites are irregular moons, while only 19 are large enough to be round. Ganymede, followed by Titan, Callisto, Io and Earth's Moon are the largest natural satellites in the Solar System (see List of natural satellites § List). A natural satellite or moon is, in the most common usage, an astronomical body that orbits a planet or minor planet (or sometimes another small Solar System body). In the Solar System there are six planetary satellite systems containing 175 known natural satellites.
