Rendezvous in Cis-Lunar Space near Rectilinear Halo Orbit: Dynamics and Control Issues

The paper presents the development of a fully-safe, automatic rendezvous strategy between passive vehicle and an active one orbiting around Earth–Moon L2 Lagrangian point. This is critical phases future missions to permanently return Moon, which are interest majority space organizations. first step in study derivation suitable full 6-DOF relative motion model Local Vertical Horizontal reference frame, most for design guidance. main dynamic approximated using both elliptic circular three-body motion, due contribution Earth Moon gravity. A rather detailed set sensors actuator dynamics was also implemented order ensure reliability guidance algorithms. selection control presented, evaluated sample scenario as described by ESA’s HERACLES program. safety, particular concept introduced different techniques guarantee it discussed that exploit ideas stable unstable manifolds intrinsically some properties at each hold-point, trajectory divided. Finally, validated available Ephemeris models verify validity results their limitations more design.
