微小卫星集群在有界空间表面的均匀分布策略

考虑微小卫星集群在轨服务的任务效率及星群在有限空间区域表面均匀分布的任务需求,提出基于改进独占球与势函数相结合的空间集群均匀分布度量模型和构型控制策略,该策略可以有效度量航天器集群空间均匀性、空间覆盖性和空间聚集性指标,并指导航天器集群在有限区域内实现无碰撞自组织的均匀分布构型.仿真分析表明,均匀度模型具有良好的旋转对称性和平移对称性,可以有效指导集群实现均匀分布并具有良好低维投影均匀性.

Uniform distribution strategy of microsatellite swarm on bounded space surface

According to the efficiency of on-orbit service and the requirements of uniform distribution on the bounded space surface for satellite swarm, a distribution measurement model and corresponding configuration control strategy based on the combination of the improved monopolize ball and the potential function are proposed. It can measure the spatial uniformity, spatial coverage and spatial clustering index of satellite swarm effectively, and guide the satellite swarm to build the self-organizing uniform distribution without collision under the condition of limited awareness information in a limited area. Simulation analysis shows the good rotational symmetry and translational symmetry of the uniformity model, as well as the distribution uniformity of satellite swarm with good low dimensional projection shown.
