Abstract

The problem of planar spacecraft docking in close proximity to an object rotating on the plane at a constant rate was examined through reachability analysis. The main contributions of this work are the development of a linear system representing the relative dynamics for the scenario of interest and visualization of the backward-reachable sets representing initial conditions from which a docking maneuver is feasible. The results showed that as the chief’s rotation rate increases and control authority decreases, docking becomes more difficult, if not infeasible. It was also shown that, in some cases, a higher rotation rate may help achieve a feasible condition.
