Abstract

Satellite-to-Satellite Tracking in low-low model (SST-ll) is a new technique to resolve the series of problems met in the determination of the earths gravity field. As the key technique of SST-ll, KBR can get SST-ll measurements directly. So the KBR performance analysis is the first step in SST-ll design. In this paper, assuming that the satellite pairs of SST-ll are in near circle polar orbits, the spectrum relationship between the earth gravity field and KBR is established using analytic method. And then some examples are analyzed, the suggestions and conclusions are drawn from these examples. The research results could be taken as a reference for future satellite gravity project of China.
