Abstract

Passive safety of flight constraints for orbital rendezvous and proximity operations trajectory design are imposed as a means for ensuring zero probability of collision in the event of a passive failure on the chaser satellite. For a chaser satellite near a target satellite in a near circular reference orbit, relative orbital elements are used to develop safety of flight constraints. Using relative orbital elements, the problem is formulated as a minimum ∆v convex optimization problem in which the optimal transfer trajectories are guaranteed to not pass within a prescribed distance of the target satellite in the event of a passive failure such as power loss, computer shutdown/reboot, or a suspension of normal activities due to mission/vehicle anomalies. The nonconvex constraints are convexified via linearized approximations and implemented in a sequential convex optimization problem.
