WebSo each GPS satellite has an atomic clock, the most stable and accurate time reference ever developed (using the element Rubidium most of the time), and it uses that clock to broadcast its time. Atomic clocks in satellites are expensive ($50-100k) and big, but today you can get one for $1500 that fits in your pocket. Your GPS receiver does not ... 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)!
