Relativistic Time Transfer in the Solar System

Relativity has become an important aspect of modern precise timekeeping systems. Thus, far from being simply a textbook problem or merely of scientific interest, the analysis of relativistic effects on time measurement is an essential practical consideration. This paper outlines the fundamental concepts of relativistic time transfer and describes the details of the mathematical model. The magnitudes of various relativistic effects for clocks on GPS satellites, other Earth satellites, on Mars, or on the Moon are derived.
