摘　　要：提出了一种新的考虑避碰约束的编队队形重构路径规划方法。首先通过常规编队重构规划方法得出各星的机动策略,以此预测重构过程中各星最小距离,将此最小距离大于安全距离作为约束条件,重新规划出队形重构轨迹。仿真结果表明,该方法计算量小,能够快速地规划出考虑避碰约束时的队形重构卫星机动轨迹,且能有效节省能量消耗。A new satellite formation reconfiguration method considering the collision avoidance constraint was proposed.At first,each satellite motivation trajectory was calculated by the normal formation reconfiguration method,by which the minimal distance between each satellite during the reconfiguration phase was forecasted.Then,with the minimal distance larger than safe distance as the constraint condition,to replan the formation reconfiguration trajectory.Simulation results manifest that the mehod is with a low computational complexity,the formation reconfiguration trajectory can be obtained rapidly,and can reduce the fuel consumption.
