Relativistic Effects on Satellite Clock as Seen from Earth
Relativistic Effects on Satellite Clock as Seen from Earth
The general theory of relativity implies time contraction due to the Earth's gravitational field. A clock on a satellite appears to run faster when observed from the surface of the Earth.
The special theory of relativity predicts time dilation. A clock on a fast-flying satellite appears to run slower when observed from a stationary position on Earth.
It is possible to observe the combined effect of general and special relativity on an atomic clock on board a GPS satellite.
