A Modified Targeting Strategy for Station-Keeping of Libration Point Orbits in the Real Earth-Moon System

In this paper, a modified targeting strategy is developed for missions on libration point orbits (LPOs) in the real Earth-Moon system. In order to simulate a station-keeping procedure in a dynamic model as realistic as possible, LPOs generated in the circular restricted three-body problem (CRTBP) ar...
