GPS satellites carry atomic clocks that provide extremely accurate time. The time information is placed in the codes broadcast by the satellite so that a receiver can continuously determine the time the signal was broadcast. ... Thus, the receiver uses four satellites to compute latitude, longitude, altitude, and time.
