For the navigation of Lunar Exploration Rover (or Lunar Rover Vehicle, LRV), localization is one of the most important problem.

Based on the concept and main functions of lunar rovers,system design including composition of subsystems,operational states and modes is analyzed and investigated.

The lunar exploration mission requires a long-range autonomous navigation of lunar rover,heading information is an important part of lunar rover navigation,its precision will affects the localization precision and the performance of navigation directly,especially for long range,long duration traverse on the moon.

The significance of lunar rover localization is introduced first,and the corresponding limitations of all localization algorithms are indicated by analyzing the lunar environment.

Then,it summarizes the eight exploration rovers that has been launched onto the lunar and Martian surface successfully and made exploration.

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.
