Analysis of GPS Satellite Ephemeris Parameters Fitting Algorithm

Zeng Zhi-ling

Abstract

Satellite broadcast ephemeris fitting is one of the basic works of the ground control segment.In order to analyze the precision and efficiency of GPS satellite ephemeris fitting,the observation model of estimating GPS satellite ephemeris parameters by satellite positions was derived.The efficiency of the algorithm and satellite position error effect was analyzed.The result showed that the algorithm presented in this article was feasible and efficient.
