地月转移轨道的天基测向初轨确定研究

研究了利用天基测向数据对地月转移轨道的初轨确定。天基平台分别考虑采用单颗卫星和星座卫星,研究了观测数据的噪声平滑,分析了观测弧段长度和观测几何对两种平台的定轨精度的影响,基于数值分析结果,研究了初定轨中系统差的消除。研究结果表明,星座双星同步定轨比较适用于地月转移轨道的天基测向初定轨。

Research on Initial Orbit Determination of Cislunar Transfer Trajectory with Space-based Angle Measurements

Initial orbit determination of cislunar transfer trajectory with space-based angle measurement is discussed.The measurement platforms include a single satellite and two constellation satellites.First,the smoothness of noise is studied.Second,the effects of arc length and measurement geometry on the orbit determination precise are analyzed.Finally,the disposal of model errors is addressed.According to the research,the constellation synchronized orbit determination is preferred for the initial orbit determina...
