Through the analysis on kinematical constraint characters of the launch window for Earth-to-Moon transfer trajectories based on the high elliptical parking orbit,laws of kinematical constraint influence on the launch window are given,and launch opportunities of the lunar probe and the probability to add the launch window are verified.

This paper studies the attitude large angle slew problem that rate and control moment of the lunar probe are limited.

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.
