| 摘要: |
| 提出了一种新的考虑避碰约束的编队卫星入网路径规划策略。首先通过常规编队卫星入网的多脉冲线性规划方法,得到一组卫星入网的脉冲序列,以此预测轨道机动过程中各星之间的最小距离,当最小距离小于安全距离时,将最小距离前后脉冲施加时刻的相对位置作为约束条件,重新规划卫星入网轨迹,迭代进行直到满足避碰要求。仿真结果表明,该方法由于减少了路径规划过程中约束条件的个数,能够快速地规划出考虑避碰约束时的编队卫星入网轨迹,且有效节省燃料消耗。 |

| Abstract: |
| A new trajectory planning method for satellite formation is proposed with collision avoidance considered.Sections 1 and 2 of the full paper explain our new method, which we believe is better than existing ones and whosecore consists of: "First, based on the multi-impulse linear programming method, the maneuver sequences are ob-tained for the satellite formation, with the shortest distance between satellites predicted during orbit maneuvers. Ifthe shortest distance is smaller than the safe distance, a new trajectory planning is reprogrammed. The process is it-erated untill the trajectory planning satisfies the collision avoidance constraints. "Simulation results, presented inFigs. 2 through 4, and their analysis manifest preliminarily that the computational complexity of this method is smalland the trajectory planning of the satellite formation can be programmed rapidly; besides, our analysis shows thatthe fuel cost of the orbit maneuver is lower. |
