In this chapter, the effects of the relative motion between a GPS satellite and a stationary receiver on the Earth are addressed. An analysis of the satellite motion is carried out to justify the assumption of constant relative radial speed within observation intervals adopted in the applications. It is shown that the transmitted cyclostationary signal is still cyclostationary at the receiver but with different cycle frequencies and cyclic features. Moreover, the transmitted and received signals are not jointly cyclostationary but, rather, jointly spectrally correlated. The implications of this statistical characterization on synchronization and parameter estimation problems are discussed.
