摘　　要：根据"嫦娥一1"的探测任务特点,其将在绕月段运行至少1年,本文主要讨论了这个阶段内环月卫星的可见时段及地面站的布设问题。文中阐述了可见时段的计算原理,对两种不同的地面站(局域和全球)布设方式进行了仿真计算。结果表明,全球布站较局域布站对环月卫星的可见时段明显增长,便于对环月卫星进行测控。Based on the exploration mission, the satellite of ＂Chang＇ e-1＂ will orbit the moon for at least one year. The paper mainly describes the problems of the visible time of the circumlunar satellite and the distribution of the ground stations. The calculation principle of the visible time is deduced and the simulation is made based on two different distributions of ground stations, which are local and global ground stations. The simulation results show that the visible time of the circumlunar satellite based on global ground stations is increased evidently compared with that based on local ground stations, which is beneficial to the measurement and control of the circumlunar satellite.
