摘　　要：全球导航卫星系统(Global Navigation Satellite System,GNSS)卫星信号在月球轨道的可见数量与时间是月球探测器利用GNSS实现辅助导航的重要因素。针对绕月卫星与月面探测器对GNSS卫星可见数量不明确、对比分析不足的问题。选择月球椭圆冻结轨道(Elliptical Lunar Frozen Orbit,ELFO)、月球波得区域(Rimae Bode)和月球南极沙克尔顿区作为分析目标,分析并统计了在不同ELFO、不同月面条件和月球南极中继条件下的GNSS卫星可见数量与可见时间。仿真结果表明,在月面波得区域,小范围移动对北斗卫星信号接收数量影响较小;在月球南极沙克尔顿(Shackleton)区,ELFO_satellite_3轨道在为月球南极区域提供导航定位期间可接收到最多4颗北斗与GPS卫星信号。运行在ELFO_satellite_3轨道的月球导航系统卫星能在运行周期内接收到最多的GNSS卫星信号。实验结果可为中国鹊桥通导遥星座系统、月面与月球南极探测器利用GNSS卫星信号进行导航定位提供参考。The visible quantity and time of GNSS(Global Navigation Satellite System)satellite signal in lunar orbit is an important factor for lunar probe to use GNSS to realize auxiliary navigation.To deal with the problems that the number of GNSS satellites visible by lunar orbiting satellites and lunar surface detectors is not clear and the comparative analysis is insufficient,this paper selected the lunar elliptical frozen orbit(ELFO),the Peter region of the moon and the Shackleton region of the south pole of the moon as analysis targets,analyzed and statistically analyzed the number and duration of visible GNSS satellites under different ELFOs,lunar surface conditions,and lunar South Pole relay conditions.Simulation results reveal that,in the Peter region,minor surface movements have minimal impact on the number of signals received by Beidou satellites;and at Shackleton,the South Pole’s ELFO-Satellite 3 orbit supports visibility of up to four Beidou and GPS satellite signals during positioning activities.The ELFO-Satellite 3 orbit demonstrates the highest GNSS signal reception within its operational cycle,offering substantial potential for lunar navigation.These findings provide valuable insights for China’s“Magpie Bridge”Navigation Remote Constellation System and future lunar probes,especially in leveraging GNSS satellite signals for navigation and positioning on the lunar surface and in lunar South Pole regions.
