Effect of Libration in Longitude on Circumlunar Time of Lunar Soft-landing Probe

摘要：

Effect of libration in longitude on circumlunar time of lunar soft-landing probe was studied. Firstly concept of libration in longitude and coordinates needed were introduced, calculation method of libration in longitude was deduced, then geometry at entry point of the lunar sphere of influence was analyzed from which an important conclusion was obtained, at last relations between circumlunar time and libration in longitude were calculated, and some simulations of the problem were given.
