摘要
论述了利用SLR检核IGS提供的GPS卫星精密轨道的方法。采用2005年9月1日到30日的SLR观测数据对IGS提供的GPS35卫星精密轨道进行了检核实验,实验结果表明,SLR观测站存在一定的系统偏差,IGS提供的精密轨道没有明显的系统偏差,其精度优于2 cm。
The technique of evaluating GPS35 satellite precise orbit with SLR measurements is presented. SLR measurements observed from September 1 to 30, 2005 are processed to compute GPS35 satellite precise orbit which is provided by IGS. Based on the SLR residual analysis, the systematic error is found in some observation stations but not in the precise orbit. The precision of GPS35 satellite precise orbit is better than 2 cm.
