A GPS receiver determines its own location by measuring the time it takes for a signal to arrive at its location from at least four satellites. If a GPS receiver calculates its distance from only one satellite, it could be that exact distance from the satellite in any direction.

GPS works by providing information on exact location. A GPS tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction.

To calculate location, a GPS device must be able to read the signal from at least four satellites. Each satellite in the network circles the earth twice a day, and each satellite sends a unique signal, orbital parameters and time. At any given moment, a GPS device can read the signals from six or more satellites.
