Autonomous Relative Orbit Determination and Tracking for Geostationary Satellites Based on the Distance Measurement

地球静止卫星之间的位置保持与控制对于提高通信容量、有效利用空间频谱具有重要意义。从星间相对运动的角度,研究以星间距离为观测量实现静止卫星的相对自主定轨,给出了系统的可观测性条件,并进一步对定轨性能进行了数值分析。

There is great importance to control the relative position of geostationary satellites.It helps to enhance the communi- cation capability and the efficiency of spatial spectrum.From the perspective of the relative moving rule between satellites,the method of autonomous relative orbit determination based on distance measurement is investigated.The condition of system observability is derived.The performance of orbit determination is analyzed in quantity and the corresponding simulation is presented.
