Space Debris Flyby Trajectory Optimization of Satellite Constellation after Mission Life
Taking the SL constellation as an example to design the optimal orbits for flyby and detection of multiple orbital planes and multiple targets from the parking orbit,a multi-target flyby program to actively remove large debris converted by constellation satellites at the end of mission life is proposed.Firstly,the orbital planes of target satellites are classified according to the orbital characteristics of the constellation.Then,the dimension of the parameters of the orbital maneuver is reduced according to the spherical geometric and Gibbs'formula,and the method of single-impulse two-satellite flyby is proposed in consideration of the cases of cruise and multi-revolution in the suppose of the Kepler orbit.Based on the flyby orbits searched by the branch and bound breadth-first algorithm in the J2-perturbed model,the flyby sequence with the minimum cost-effectiveness ratio is obtained.The simulation results show that the spacecraft can flyby 48 SL satellites through 24 maneuvers in 9.64 days with the total impulse of 1.66 km/s,which proves the effectiveness of the proposed method and is helpful for the future large-scale space debris removal missions.
