摘要/Abstract

摘要： 中国第一颗月球探测卫星“嫦娥一号”于2007年10月24日成功发射并于11月7日顺利进入了距月面200km的科学探测的使命轨道，原计划在整个飞行过程中比较关键的轨道段是地月转移轨道段。要进行2至3次中途轨道修正，而实际的飞行结果只在第41h作了一次很小的修正，所用的速度增量是4.8m/s。基于有关的实测数据对此进行详细的分析，以期获得一些规律性的认识。

Abstract:

CE-1, the Chinese first lunar exploration satellite, was successfully launched on 24th Oct. 2007 and captured into a mission orbit of 200 km from lunar surface on 7th Nov. 2007. The translunar trajectory is the key section within the whole flight process. According the original design 2 or 3 times of midcourse corrections would be performed during this orbital segment. However, only one correction maneuver has been carried out at the 41th hour after the translunar trajectory insertion and the velocity increment needed was only 4.8m/s. Some detailed analysis based on the real tracking data and the orbit determination results is presented here in this paper.

Key words: lunar exploration, lunar satellite, phasing orbit, translunar trajectory, midcourse correction maneuver
