This paper introduces a framework of purely convex programs designed for passively safe impulsive rendezvous and proximity operations in cislunar orbits, addressing maneuver execution errors and navigation uncertainties. The methods are validated through high-fidelity closed-loop Monte Carlo simulations, ensuring efficient onboard execution for autonomous missions. Notably, these techniques will serve as the foundational guidance routines for NASA's CAPSTONE 02 mission, aimed at demonstrating autonomous capabilities in a challenging orbital environment.
Passively safe guidance strategies could revolutionize autonomous space operations by ensuring reliable rendezvous even in the face of navigation uncertainties.
This paper presents purely convex programs for passively safe impulsive rendezvous and proximity operations in cislunar orbits. Approach, arrival, and abort maneuvers are all designed and validated in the context of maneuver execution error and navigation uncertainty, and formulated for efficient onboard execution in the autonomous scenario. The outlined methods form the baseline onboard guidance routines for NASA's CAPSTONE 02 mission planned to demonstrate autonomous rendezvous and proximity operations capabilities in the southern 9:2 synodic near rectilinear halo orbit. High fidelity closed loop Monte Carlo simulations using the planned relative navigation sensor suite and measurement cadence verify the intended maneuver design performance.
