摘　　要：根据J 2摄动对轨道面的长期影响规律,提出了一种在近地低轨道星座卫星之间进行异面轨道交会的解析近似方法,并用于建立多星多约束遍历交会的混合整数规划模型,能够快速获得多星交会次序、交会时刻的最优解。仿真算例表明提出的方法适用于在轨服务、构型重建等类型任务的快速优化,计算速度和燃料消耗优于以往类似算法。According to the long-term influence of J 2 perturbation on the orbital plane,an analytical approximation method is proposed for the non-coplanar orbital rendezvous between satellites in a low-Earth-orbit constellation.And then the method is used to establish a mixed integer planning model for multi-satellite rendezvous with multiple constraints,which can quickly obtain the global optimal rendezvous sequence and transfer times.Simulation results show that the proposed method is suitable for the rapid optimization of tasks such as on-orbit servicing and re-configuration reconstruction,and the calculation efficiency and fuel consumption are better than those of the previous similar algorithms.
