- The main functions of using a compass are: 1  tell which direction you are traveling - your heading. 2  tell which direction an object is from you - its bearing. 3  keep you following a straight line of travel. 4  orient a map - aligning a map with the actual land.  triangulation - determining your location with a map.

- A compass needle aligns itself and points toward the top of Earth's magnetic field, giving explorers and lost souls a consistent sense of direction.

- Well, the simplest answer is that the astrolabe pretty well had to be used at night and could not be used in bad weather. The compass, which relys on the magnetic field of the Earth rather than a visualiztion of the stars, works at any time, and in any weather. Chad Samples · 5 years ago. Thumbs up.

Best Compass Gyrocompass – This type of compass is used almost exclusively on ships. It is very expensive. This type of compass is not a magnetic compass, it finds true North which is usually 1,000 miles away from magnetic north. They use a fast spinning disc that is battery powered or electrically powered to gain the high speeds.

Compass A smartphone that can be used as a compass because of the magnetometer inside. A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions, or points. Usually, a diagram called a compass rose, shows the directions north, south, east, and west on the compass face as abbreviated initials. When the compass is used, the rose can be aligned with the corresponding geographic directions, so, for example, the N mark on the rose really points to the north.

How to use the iOS Compass for basic land navigation As Apple points out, the accuracy of the compass can be affected by magnetic or environmental interference; even the magnets in the iPhone earbuds can cause a deviation. Use the digital compass only for basic navigation assistance. Don't rely on it to determine precise location, proximity, distance, or direction..

Compass types Compasses are useful for taking bearings and for orienting the map so that it is aligned with the terrain - but it is possible, in most areas, to complete a course quite easily and efficiently without a compass (an exception: it would be difficult to navigate flat areas poor in prominent features without a compass).

Compass Watches Wenger watch with analog Compass. How to use a watch with a compass bezel. By using the position of the hour hand and the position of the sun you can determine direction. The direction will be an approximation and its important to consider that some discrepency can occur due to different latitudes and seasons.

Compass: North, South, East and West Three-Figure Bearings. Three-figure bearings are an alternative to compass bearings that are much more precise. Airline pilots and ships' helmsmen use three-figure bearings so that they can point their craft in exactly the right direction to safely reach their destination.

- Place the compass needle at any point on AB, and set the compass width to M. Place the compass needle at M, and using sufficient compass width, mark two arcs across AB . Draw a line through M that intersects AB, and mark the point of intersection. Using a convenient compass width, mark two arcs through M centered at any point on AB.

Compass types This has to do with the fact that the magnetic field lines, to which a compass needle aligns, point into the earth at the north and south magnetic poles. In the northern hemisphere the north end of the needle is pulled downwards, and the south end is counterweighted to balance the needle.

Definitions &Translations A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions, or points. Usually, a diagram called a compass rose, shows the directions north, south, east, and west as abbreviated initials marked on the compass.When the compass is used, the rose can be aligned with the corresponding geographic directions, so, for example, the N mark on the rose really points to the north.requently, in addition to the rose or sometimes instead of it, angle markings in degrees are shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270.

- If you used a compass set with 0 degrees declination in Wyoming where the declination is 12 degrees East, the compass would tell you that you're heading North when you're actually heading 12 degrees East of North.

- For example, a declination angle of 5 degrees means that magnetic north is 5 degrees clockwise from true north. Set your compass needle to point to true north. A lensatic compass typically allows you to rotate the compass needle to true north and lock it so that it always points to true north.

Compass The mariner's compass consists of a magnetic needle freely suspended so that in the earth's magnetic field it turns until aligned with the magnetic north and south poles. Declination is the angle between the magnetic needle and the geographical meridian. Use of the compass by the early Chinese is probably legendary.

How Compasses Work The reason why a compass works is more interesting. It turns out that you can think of the Earth as having a gigantic bar magnet buried inside. In order for the north end of the compass to point toward the North Pole, you have to assume that the buried bar magnet has its south end at the North Pole, as shown in the diagram at the right. If you think of the world this way, then you can see that the normal opposites attract rule of magnets would cause the north end of the compass needle to point toward the south end of the buried bar magnet. So the compass points toward the North Pole. To be completely accurate, the bar magnet does not run exactly along the Earth's rotational axis. It is skewed slightly off center.

- The compass needle points toward the north magnetic pole. That place is close enough to the earth's geographic north pole so that over much of the. earth, the magnetic compass indication can be a useful approximation of true north. 1 person found this useful.

North References for Navigating with Map, Compass and GPS Set your compass to 0°, and always think about it. 1  All bearings will be Magnetic. 2  Conversion to Grid or True, or drawing Magnetic North reference lines on your map, will be necessary for map work. 3  Works with all compasses. 4  You are more likely to remember how declination works.

Determine a Magnetic Azimuth Using a Lensatic Compass Look through the lens of the eyepiece and read the azimuth under the index line. (2) Center-hold method (Figure 5-28). Use this method only when a precise direction is not required: (a) Open the compass so that the cover forms a straight edge with the base.

Which way does the compass point in the southern hemisphere? A compass will point the same whether it is in the northern or southern hemisphere. The needle on a compass is designed to magnetically line up with the earths poles.Therefore the north end of the needle of the compass will point to earths north, and the south end of the compass needle will point towards earths south whether you are in the northern or southern hemisphere.he compass always aligns itself with the magnetic field in your locality; unless there is a magnet around, then it will point to the magnetic item.

Trigonometry/Compass Bearings The four cardinal points on a compass, which split the circumference of the compass into four equal parts, are (going clockwise) N orth, E ast, S outh and W est. Since there are 360º in the circumference, the cardinal points are separated by 360º/4 or 90º.A compass rose is shown on the right.rue north is the direction from a point to the north pole of the Earth's rotation axis. It may be determined by observations of the stars, especially (in the Northern hemisphere) Polaris, α Ursae Minoris. A magnetic compass points along the Earth's magnetic field. This direction is called magnetic north.

How to use a compass Try to see traces of human activity. If you see nothing, you should try to figure out in what direction would be the best to travel. If you haven't got a map, try to draw one if you can of the terrain in front of you, and try to mark off where north is, using the methods below. If you have got a map, try to determine where you are. Remember, you don't want to climb more hills than you have to.

- Take one of your small compasses. The arrow on the compass is magnetic and will experience a torque so that the North pole of the compass will point in the direction of the Earth’s magnetic field if no other magnetic fields are present.lace a compass at point P. Mark the needle position with two dots, and draw an arrow indicating the needle’s direction. Now remove bar magnet 1 and indicate the compass needle’s direction in the same manner as above.
