摘要
论述了利用SLR检核GPS卫星广播星历精度的基本方法。采用2005年9月1日至11月30日3个月的SLR观测数据对GPS35号卫星广播星历的精度进行了检核,检核结果表明,观测时段内,由广播星历误差所引起的用户等效距离误差约为35cm。由此我们可以得出结论,在观测时段内GPS35号卫星广播星历的精度能够保障导航和实时定位工作的要求。
The technique of evaluating GPS satellite broadcast ephemeris precision by using SLR data is presented. In this paper, we use SLR data observed from September 1 to November 30, 2005 to compute GPS35 satellite broadcast ephemeris precision. Based on the SLR residual analysis, it is found that the URE（User Equivalent Remove Error）which is caused by broadcast ephemeris error is about 35cm. Thus, we can conclude that GPS35 satellite broadcast ephemeris precision can satisfy navigation and Real-time orientation in observation period of time.
