In this dissertation, the design and optimization of lunar probe orbit has been studied by using the theory and method of spacecraft orbital dynamics, aiming at to launch polar moon satellite from the earth parking orbit, and considering synthetically the problems about the launcher energy, flying time, launch window and orbit navigation. The flying conditions, program and orbit of the lunar probe are given.

本论文利用航天器轨道动力学理论和方法，以从地球停泊轨道入轨点出发发射月球极月卫星的轨道为对象，综合考虑运载能力、飞行时间、发射窗口、轨道导航等问题，进行月球探测器轨道设计与优化，给出月球探测器的飞行条件、程序及其轨道。

Chapter 3 analyzes numerically the effects for orbit calculation caused by orbital perturbation, parameter error and so on. A precise mathematical model of orbit calculation is given.
