地面站对月球探测器的导航

Navigation for the Lunar Probe Based on Ground Tracking Sites

针对一个从地球停泊轨道出发绕地月飞行的月球探测器 ,讨论地面站对月球探测器导航的几个问题 ,包括观测方式的选取、地面站的分布、制导点的调整、导航精度等。结果表明仅依靠局域的地面站 ,采用测距的方式 ,可以对探测器进行实时导航。

Taking an lunar probe around the earth and the moon from the earth parking orbit for example, we analyze some questions of navigation of the lunar probe based on ground tracking site, including the choice of tracking type, distribution of ground tracking site, adjustment of the guiding time, and accuracy of navigation. It is verified that the lunar probe can be navigated in real time by ranging data based on the local ground tracking site. The method and result of the research may serve as reference for the practical engineering of lunar probe.
