摘要： 对探月巡视器在静止状态和移动状态下的测控状态包括高低角和方位角进行了计算分析,计算考虑了理论状态以及叠加了虚拟地形的两种情况,分析了月表地形起伏对测控状态的影响。文章首先给出了着陆点在理论静止状态下高低角和方位角的计算结果以及与卫星仿真工具包(STK)的比对分析情况;其次考虑到月表地形的存在,构造一种虚拟地形,在月球车给定的行走路线上分析了地形对测控方位的影响。

Abstract: A kind of simulation method was introduced to simulate the moon rover static & mobile measurement and control(TMTC) status including azimuth and elevation.The method covered immobile and locomotive status with and without terrain.Theoretical azimuth and elevation of landing point were given and compared with Satellite tool kit(STK).Considering a kind of virtual moving route,the influence of given terrain on the rover TMTC status was worked out.
