| 摘 要： | 为评估测量时刻偏差对单星定轨等效测量误差的影响，根据单星定轨处理策略分析了其理论模型，指出测站接收机的测量时刻偏差由测站时钟钟差以及测量时刻不准确度等组成。试验数据分析表明，测站钟差经一阶多项式拟合后的残差可近似为零均值的测量噪声；数值仿真结果表明，卫星信号发射时刻1ms误差导致GEO、IGSO、MEO三种卫星的等效测距误差分别为006cm、40cm、80cm。

| Abstract: | To evaluate the effect of measuring time bias on single satellite orbit determination(SSOD) error,the theoretical model based on the SSOD strategy was analyzed.The measuring time bias of monitor station receiver was composed by clock error and measuring time uncertainty.The experiment data analysis results show that the clock residual error of monitor station after fitting by 1st order polynomial is approximately taken as noise with zero mean.The simulation results show that the equivalent ranging error for... |
