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

. Because radio waves travel at a constant speed, the receiver can use the time measurements to calculate its distance from each satellite.

A GPS receiver calculates its position

by precisely timing the signals sent by GPS satellites high above the Earth

. Each satellite continually transmits messages that include the time the message was transmitted and the satellite position at the time of message transmission.
