Study on lunar gravity field and orbit control of lunar satellite

In this paper, with the globally-accepted lunar gravitation field models LP165P and GLGM-2, character of the lunar gravitation field models were analyzed based on kaula theory. Then, making use of LP165P models truncated to 70 orders and degrees, the free running time span of lunar satellite of 100km height were given. Last, a maneuver method for orbit height keeping is presented for 100km height orbit. The result of this paper deduced time consuming of the computer and reached certain precision when using lunar gravitation field models.
