摘要: 为了降低"一对多"在轨服务的成本,以共面圆轨道卫星群为研究对象,开展了在轨服务任务规划问题的研究。首先,对"一对多"在轨服务任务场景进行了分析,建立了任务规划数学模型,将其简化为包含内层Lambert问题、外层最优时间分配问题的双层优化模型。然后,给出了任务规划求解方法及流程,提出采用工程图解法的思想求解内层多圈Lambert问题,采用遗传算法求解外层最优时间分配问题。最后,以三个目标航天器为例,针对限制和不限制在轨服务任务完成总时间这两种情况,采用上述方法进行求解,计算结果验证了方法的有效性。

Abstract: In order to reduce the cost of on-orbit service,the programming of on-orbit service mission for multiple object spacecraft in coplanar circular orbits was studied.First,the mission scenario was analyzed and the mathematic model was set up.The mission programming was a bi-layer optimization problem,and the outer layer was an optimal time distribute question while the inner layer was the multiple-revolution Lambert problem.Secondly,the solving method and its corresponding step were given.The inner layer problem was solved by a scheme method and the outer layer problem by the genetic algorithm.Finally,take three object spacecrafts as example,the programming problem was solved under two conditions that the mission time was limited or not.The results validate the efficiency of the method.
