Atomic clocks, correct to the billionth of a second, made GPS tracking possible. GPS works through receivers which compute location through geometry and trigonometry, figuring the difference in the arrival time of signals from four or more of the satellites. Location may be pinpointed within a very small area, and with some devices, even less. Currently, GPS devices can be cellular based, wireless, or satellite.
