WebA calculation using General Relativity predicts that the clocks in each GPS satellite should get ahead of ground-based clocks by 45 microseconds per day. The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)! WebHow Do Atomic Clocks Work? You know what a pendulum in a grandfather clock is, right? It is a harmonic oscillator that uses gravity to swing back and forth, and this motion helps the clock keep time. Well, the natural way that atoms oscillate works similar to a …
