How GPS devices use satellites and atomic clocks to help with navigation

NEW MEXICO (KRQE) – Have you ever wondered how the GPS in your phone or your car and pinpoint your location with such accuracy?  It's a matter of time atomic time, to be precise. The triangulation of satellites, ground towers, and your device is made possible by the use of atomic clocks. Atomic clocks work in a similar method as a pendulum or quartz clocks:  the oscillation of the time-keeper is kept in line with an exterior "kick", which ensures friction
