Fully Safe Rendezvous Strategy in Cis-Lunar Space: Passive and Active Collision Avoidance

Abstract The future assembly of the Lunar Orbital Platform Gateway, on a near 9:2 resonant Rectilinear Halo Orbit, requires necessity designing safe and reliable strategies to perform rendezvous docking with station. paper describes tests strategy guarantee safety an entire manoeuvre in proximity Moon L2 Lagrangian point respect specific set failures. far range is guaranteed through automatic allocation selected hold-points, whereas during close actively presence main goal contribute very limited literature about autonomous design guidance for non negligible third body influence, where considerations are paramount. proposed approach based exploitation manifold theory used circular restricted three problem model passive far-range section, optimal active collision avoidance approach.
