Bearings-Only Guidance in Cis-Lunar Rendezvous
The current plans of returning to the Moon involve rendezvous and docking/berthing operations
with a passive permanent station, whose targeted orbit is a Near Rectilinear Halo
Orbit. In this work a preliminary guidance algorithm for the close-range rendezvous phase
is proposed, based on a sample mission application, assuming the active chaser can measure
relative angles only to the target. The navigation performance is affected by the maneuvers
performed because their execution is necessary to make the problem observable. The relative
motion equations with third body perturbation are considered directly in the guidance
algorithm, with the additional aim of improving observability during the approach trajectory.
Numerical simulations are presented to validate the proposed methodology
