| 摘 要： | 提出了一种利用星间单差法消除接收机钟差的GEO卫星精密定轨方案。通过仿真,详细探讨了相关原理、参数设置、测站分布以及单差选星等关键问题。仿真研究表明,该方法消去了接收机钟差、大部分与测站相关的系统误差以及用模型未完全改正的对流层及电离层延迟残差,能够直接解算卫星轨道参数,减轻测站接收机时钟同步的负担;通过方案对比,确定了一种优化方案,选取合适的卫星对,在现有条件下采用合适的测站分布,利用星间单差方法解算22参数,可以获得高精度的GEO卫星轨道。

| Abstract: | In this paper,a novel scheme of GEO orbit determination was proposed,which cancelled out the receiver clock error and others system errors by single difference(SD) between the two observations of different satellites at the same epoch on the same station.The basic theory and some key techniques of parameter selection,station distribution and reference satellite selection,etc.were discussed in detail by simulation cases.The simulated results reveal that the receiver clock error could be cancelled out and the... |
