Definition
An architecture using libration point orbit satellites to relay communication signals between lunar surface facilities and Earth. First proposed by Farquhar in 1967 to solve the problem of the lunar far side being unable to directly communicate with Earth. This paper extends the concept to the lunar south pole: an inter-satellite link is also established between the two spacecraft, enabling relay through the other satellite when one has line-of-sight to the lunar surface but is blocked from direct Earth communication by the moon.
Application Value
During the orbit design phase，can be used toanalyzespacecraftin cislunar space的motion characteristics，evaluatedifferent orbital schemes的feasibility与efficiency. 保障月球背面与地球之间的持续通信，是构建月球通信网络的keytechnology. used foranalyzeperiodic orbit的stability与transfer characteristics，supportcislunar space stationorbital designscheme.
