Mitigating the Impact of Momentum Unloads on Station-Keeping Around Libration Point Orbits

Station-keeping maneuvers are required to maintain a spacecraft close to a Libration point orbit, where the size of these maneuvers depends on different perturbations and any unmodeled forces. In many missions, despite being small, frequent momentum unloads can have a large impact on the size of station-keeping maneuvers. In this paper we will show that applying momentum unloads in the Linear Approximation of the Non-Escape (LANE) direction can significantly reduce their impact on the station-keeping delta-v budget.
