Abstract
The effect of non-spherical perturbation of Moon and perturbation of Earth on low-space lunar satellite orbit was studied in this paper. First, with the globally-accepted lunar gravity models LP165P and GLGM-2, character of the lunar gravity models were analyzed based on Kaula theory. Then, making use of LP165P models truncated to different orders and degrees, lunar satellite orbit with 50km height revolutionary was compared in order to support the idea that lunar gravity model can be truncated appropriately. Meanwhile, the free running time span of lunar satellite with 50km and 200km height were given respectively. Last, lunar satellite orbit elements were given after analyzing perturbation of Earth. The conclusion in this paper is of theoretical reference value for lunar orbit maneuver.
