Abstract : In this report, a detailed and formal derivation of the relativistic doppler shift is given. The derivation, which is devoted to persons unfamiliar with relativity, considers the effects of the motions of the source and receiver, the gravitational field of the earth, and the refraction due to the atmosphere in a unified treatment. The relativistic effect on satellite clock observations is derived, and the implications of this effect for APL satellites is discussed. An experiment to check the consistency of the predicted relativistic clock drift with the computed satellite frequency, using the Doppler Tracking Program, is described.
