"The cesium or rubidium clocks in the GPS satellites operate at 10.22999999545 MHz rather than the nominal 10.23 MHz to compensate for both the special relativity effect of a moving source and the general relativity effect of operating from a point of higher gravitational potential. The master clock at the GPS control center near Colorado Springs is set to run 16 ns a day fast to compensate for its location 1830 m above sea level."
