As a car GPS tracking device is widely used in various human activities. Not only on aircraft, ships, freight cars (vehicle tracking) is used, but also serves as a personnel-tracking systems for individual interests. Global Positioning System as a tracking system is of course a bit 'more complex to learn. Here are instructions for beginners, a basic description of this device.
Concept of the GPS system
Portable GPS
First GPS satellites in orbit around the Earth 2 Times a day
2 Global Positioning Sytem each satellite transmits data to the ground, and data signals are used to calculate the position of a point on earth
3 To calculate the location, the time differential GPS on their merits in terms of distance from the GPS satellites to calculate the Earth's surface or to a GPS receiver on Earth.
4 To calculate a position, it requires at least three GPS satellite signals to be detected by our> GPS Receivers on the ground. Getting signals from GPS satellites, you can calculate the two-dimensional position of the x and y
5 When a GPS receiver capable of receiving at least four satellite signals, then we can calculate a 3-dimensional position (x, y, z = height)

Global Positioning System Accuracy
1 Many factors affect the accuracy of position measurements, one of which is the atmosphere.
2 As a tracking system for the aircraft can use the GPS accuracyabout 5 meters.
3 To be used to further improve the accuracy of positioning, a device called WAAS (Wide Area Augmentation System), which offers an accuracy of ± 3-8 meters. WAAS system does not require special equipment to receive the WAAS signals, as long as there is no GPS or WAAS ground
4 Used to further improve the accuracy of DGPS is to increase the precision of ± 3-5 meters.
Global Positioning System satellites
1 First Global Positioning SystemSatellite was launched in 1978 and until 1994 there were 24 GPS satellites. Therh are more than 30 GPS satellites now.
2 The Global Positioning Satellite Sytem average age is 10 years, so when he was over 10 years doing maintenance, or be replaced.
Global Positioning System satellites 3 ft ± £ 2,000 average weight (± 1 ton), solar panels wide ± 17 / ± 5 meters, power transmission
