【摘要】 大规模卫星集群是未来航天领域一个重要发展方向,但如何在卫星有限资源约束下保持集群系统较长时间内的构型相对稳定是进行卫星集群应用的前提条件。本文研究了卫星集群相对动力学模型,提出了自然伴飞初始化构型策略,采用基于J2能量匹配条件给出了集群伴飞初始相对状态的方法,实现了大规模集群长期相对有界的构型。仿真表明所采用的集群初始化构型设计方法能够明显减小相对轨迹漂移。更多还原

【Abstract】 Large scale satellite swarm have been a major area of research over the past decade,but how to keep the configuration of the swarm system relatively stable for a long time under the constraint of limited satellite resources is the prerequisite for satellite swarm application. In this paper, the relative dynamic model of satellite swarm is studied, and the initialization configuration strategy of natural companion flight is proposed. The method of initial relative state of group companion flight is given based on J2 energy matching condition, and the long-term relatively bounded configuration of large-scale swarm is realized. Simulation results show that the swarm initialization configuration design method can significantly reduce the relative trajectory drift.更多还原
