A two-level scheme for multiobjective multidebris active removal mission planning in low Earth orbits

This paper proposes a two-level multiobjective multidebris active removal mission planning scheme for a multi-nanosatellite active debris removal platform. This scheme consists of a high-level thorough multiobjective transfer planning model to quickly explore a solution space and a low-level trajectory planning scheme to achieve precise rendezvous. A special point orbital maneuver strategy is proposed to coordinate with the impulsive drift-orbit transfer strategy, which resolves the corresponding rendezvous solutions after obtaining multiobjective nondominated transfer solutions. Experiments were conducted to evaluate the architecture of the novel mission planning scheme. The results demonstrate that the multiobjective transfer planning can produce a comprehensive Pareto front for all viable transfer solutions, and the converted corresponding maneuvers can achieve precise rendezvous, which effectively accomplish the goal of multidebris active removal mission planning.
