GPS Concept

First GPS satellites around the earth moves in orbit position 2 timesonce
Every second global positioning satellite signals can transmit data signals Sytem to country and are used to calculate the position of a point on earth
To calculate the third position, the GPS sends the time difference, the earth is calculated as the distance from the GPS satellites in earth surface or a GPS receiver.
To calculate the fourth position, the GPS requires at least three GPS satellite signals with which our dataReceivers on the ground. By receiving signals from GPS satellites, calculate y two-dimensional position x
Fifth, if a GPS receiver can receive at least four satellites, then we (the calculation of a three-dimensional position x, y, z = height)

Global Positioning System Accuracy

Many factors influence the accuracy of first position, one of them is the atmosphere.
Since the monitoring system according to the application of flight, the GPS can achieve accuracy of about5 meters.
Third, to further improve the positioning accuracy, a system called WAAS (Wide Area Augmentation System) is used, the precision of ± 8.3 m. Offers WAAS does not require special equipment to receive signals from WAAS, provided GPS or WAAS Ground
Fourth of further improving the accuracy of DGPS, the increased precision of ± 5.3 meters.

Global Positioning System satellites

Before the first Global Positioning System satellites launchedin 1978, and by the year 1994 were 24 GPS satellites. Therh GPS satellites are more than 30 hours.
According to the Global Positioning Satellite Sytem average age is 10 years, so if you go beyond 10 years of continuous maintenance to be done or replaced.
Third pound weight Global Positioning System satellites means ± 2000 m (± 1 tonne), solar panels wide ± 17 / ± 5 meters, Power Transmission
