多目标群的在轨服务飞行器部署策略

The deployment of on-orbit service vehicles for multi-objective group

为满足轨道分布较集中的多航天器目标群体的在轨服务需求,研究利用多艘在轨服务飞行器(OSV)的轨道组网,对目标所在空域实现完全覆盖.以各类导航星座群体所在连续空间范围的覆盖为算例,利用轨道动力学二体问题模型和立体几何学的空间截面关系,根据一定机动能力的服务飞行器的可达范围,得出多艘服务飞行器的轨道部署策略,实现对目标群所在空域的高度和倾角范围实现完全覆盖.这种确定多艘OSV数量和轨道分布的方法和步骤,为研究多OSV的空间部署和"多对多"轨道机动问题开辟了新的思路,具有一定的理论参考价值.

In order to meet the on-orbit service demands of multiple spacecraft objective group in concentrative orbit distribution,the deployment of multiple on-orbit service vehicles（OSV） to cover the target space area was studied.Considering the coverage of the continuous space area of various navigation constellations,and combining twin-body dynamics and the three-dimensional geometry principles,a deployment solution for multiple OSVs to cover the height and inclination range of the target area was presented,according to the servicing area of each OSV with the same maneuverability.The algorithm for obtaining the OSVs＇ quantity and orbit distribution provides a new idea for solving deployment problems of multiple OSVs along with multi-multi maneuvering problems,providing a theoretical reference value.
