巨型低轨星座安全性研究及其规避机动策略综述

Security Research and Maneuver Avoidance Strategy of LEO Constellation

随着星座卫星数量的不断增加,星座安全性和规避机动策略研究对于星座长期稳定运行具有重要意义。通过研究国内外文献,首先介绍了典型巨型低轨星座发展现状,其次对星座卫星间以及星座与其它物体碰撞情况进行了详细分析,给出了巨型低轨星座关键指标对空间环境的影响。最后梳理了现有星座卫星碰撞规避策略,结合巨型低轨星座面临的碰撞特点,最终选择了一种基于停泊轨道的方法作为巨型低轨星座规避机动的最佳策略。

With the increasing number of constellation satellites,the research on constellation security and evasive maneuver strategy is of great significance for the long-term stable operation of constellation.Based on the research of domestic and foreign literatures,this paper firstly introduces the development status of typical LEO constellation,and then analyzes the collision between constellation satellites and other objects in detail,and gives the impact of key indicators of LEO constellation on space environment.Finally,the collision avoidance strategies of the existing constellation satellites are sorted out.Combined with the collision characteristics of the LEO constellation,a method based on parking orbit is selected as the optimal strategy for LEO constellation collision avoidance maneuver.
