  A GPS receiver uses trilateration to determine its position on the surface of the earth by timing signals from three satellites in the Global Positioning System. The GPS is a network of satellites that orbit the earth and send a signal to GPS receivers providing precise details of the receiver's location, the time of day, and the speed the device is moving in relation to the three satellites
