Highlights Two simple novel station-keeping stategies around triangular libration points in the realistic Earth-Moon system are proposed. Both strategies do not require a pre-determined nominal orbit, and both can be extended to the case of a pre-determined nominal orbit. The robustness of the two strategies is tested by considering errors from the force model, the maneuvers, and the orbit determination process.
Abstract Concerning the unstable motions around triangular libration points in the Earth-Moon system, two simple station-keeping strategies are proposed. One is based on continuous low-thrust maneuvers, and the other is based on impulsive maneuvers. For the first strategy, its advantage is that the station-keeping process is completely decoupled from the orbit determination process. For the second strategy, the annual station-keeping cost can be as low as less than 4 m/s while maintaining a reasonably small orbit. For both strategies, the maneuvers are computed either by reference to the libration point itself, or by reference to a pre-determined nominal orbit. The two strategies are firstly proposed in the simple ephemerides model, and then verified in a simulated realistic model which considers force model uncertainties, maneuver errors, and orbit determination errors.
