Error Sources of Satellite-borne GPS and Accuracy Analysis of Precise Orbit Determination

Qiaoli Kong

Abstract

A variety of error sources have great impacts on the precision of satellite orbit determination when GPS data onboard LEO(low earth orbiter) are used.The error sources of GPS data onboard CHAMP are analyzed,and the precise orbit determination results are compared with the precise scientific orbit products released by Germany GFZ.The experimental results show an error analysis basic for precise orbit determiniation of CHAMP satellite.
