Abstract This paper presents a trajectory planning algorithm to optimise the collision avoidance of a chasing spacecraft operating in an ultra-close proximity to a failed satellite. The complex configuration and the tumbling motion of the failed satellite are considered. The two-spacecraft rendezvous dynamics are formulated based on the target body frame, and the collision avoidance constraints are detailed, particularly concerning the uncertainties. An optimisation solution of the approaching problem is generated using the Gauss pseudospectral method. A closed-loop control is used to track the optimised trajectory. Numerical results are provided to demonstrate the effectiveness of the proposed algorithms.

    Highlights Complex configuration and tumbling motion of the failed satellite are considered. A model of relative motion is established in the target body frame. Collision avoidance constraints are derived. Propagation of the optimized solution is investigated. Numerical results validate the efficacy of the proposed method.
