Abstract:

In recent years, fuel-efficient station-keeping techniques have been developed for the planned Lunar Gateway mission to a near rectilinear halo orbit (NRHO). Station-keeping approaches that rely on an autonomous navigation system that doesn't require communications with Earth are particularly important for ensuring safety and reliability. This paper presents a targeting approach for NRHO station keeping based on sequential linearization and evaluates its performance in a closed- loop simulation with a state estimator that receives position measurements from horizon-based optical navigation (OPNAV). Simulation results indicate an annual station-keeping cost (delta-v) of about 1.14 m s-1 for the proposed OPNAV-based station keeping.
