【摘要】 地球静止轨道卫星(GEO)在北斗卫星导航系统(Compass)的卫星导航中具有特别重要的作用,除了利用导航系统自身的伪距相位以外,利用其他的测轨系统对其进行精密定轨有着重要的意义。利用国家授时中心的转发式测轨网对Compass的GEO卫星进行观测,获取转发式测轨数据,利用该数据对Compass的GEO卫星进行精密定轨分析。分别从观测数据的观测精度,定轨残差以及轨道重叠误差等方面分析GEO卫星的定轨精度。更多还原

【Abstract】 GEO satellites play a significant role in Compass satellite navigation system.So it has important significance using other orbit measurement system for its precision orbit determination,using itself pseudo-range and phase measurement.Observing data has been obtained through transponder ranging system build by national time service center,Chinese academy of sciences.This paper makes the orbit determination for Compass-GEO satellite using transponder ranging data,analyze the accuracy of orbit determination through measurement accuracy,orbit residuals and orbit overlap respectively.更多还原
