GPS stands for global positioning system, they can receive the signals form satellite. GPS systems use satellites as reference points, and in fact are quite simple devices. GPS receivers are patched into a system of 27 satellites orbiting the Earth. The GPS receivers passively receive satellite signals, not transmit.

A second signal from another satellite narrows the possible locations to a circle, and then a third signal narrows it to only two possible locations for the receiver.

When a person attempts to find his or her location, the GPS receiver picks up signals from three or more of the closest satellites. Each satellite measures GPS Receivers as a distance from the satellite. With more measurements comes greater accuracy, since each new measurement helps to precisely identify the exact location of the person on earth.
