共面圆轨道航天器在轨服务任务规划

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。

Programming of On-orbit Service Mission for Multiple Object Spacecrafts in Coplanar Circular Orbits

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 probl...
