A trajectory planning method for proximity operations of heterogeneous formation satellites
In view of the on-orbit service mission using formation satellites,a cooperative operation scheme for the multi payload heterogeneous satellite cluster is proposed.Firstly,considering the inter-satellite autonomous communication,a formation system consisting of an observation satellite for main fault identification and several operational satellites for main maintenance and replenishment is established.Secondly,a multi-satellite cooperative trajectory planning method based on cyclic alternating strategy is proposed,and the satellite trajectories are optimized based on differential evolution algorithm.Finally,combined with case simulation,the impulses required by each member satellite in the formation control process and the overall safety performance of the system are analyzed.The simulation results show that the heterogeneous formation system can quickly plan the in-orbit service trajectory with high safety and robustness,which has certain engineering application value.
