Abstract

Rendezvous and proximity operations are becoming more complex, requiring autonomy and the use of more sophisticated, computation-based, guidance and control techniques. Implementing such algorithms in an autonomous system raises important questions on maneuver feasibility. In this paper, backward reachability analysis is conducted in order to visualize a set of initial conditions from which a desired rendezvous maneuver is feasible within a given amount of time and control constraints. A roto-translational model of the spacecraft relative motion is derived. An analysis method is proposed, using minimum-time optimal control solutions, to visualize backward reachable sets of this complex dynamic system.
