利用SLR及伪距数据进行卫星预报钟差精度验证

Validating Clock Bias of Satellite Using SLR and Pseudorange Data

论述了综合利用SLR和伪距观测数据进行导航卫星预报钟差精度评估的原理及计算步骤。分析了该方法所能达到的精度,并进行了可行性验证。采用2005年的观测数据对广播星历预报钟差精度进行了评估,给出了有益的结论。

The theory and method for validating satellite clock offset using SLR and pseudor-ange data are presented. The precision of this method is evaluated, and the feasibility is vali-dated. The clock precise of forecasting broadcast ephemeris is validated using the data of 2005. Some useful conclusions are presented.
