AI 中文摘要
卫星的寿命末期支撑是提升任务后处置合规率、维护空间环境的必要环节。采用激光等低推力的离轨任务会对目标产生低水平减速，逐步降低目标轨道高度；由于此类低推力轨迹耗时较长，碰撞风险会极大影响任务成功率。在此背景下，本文评估低推力离轨轨迹期间的碰撞风险，还开展了再入时间与碰撞风险关系的参数研究。
英文摘要
End-of-life support of satellites is necessary to improve post-mission-disposal compliance rates for maintaining space environment. Deorbit mission with low thrust, e.g. a laser, induces a low-level deceleration on the target object that gradually lowers the target altitude. Since such a low-thrust trajectory is time-consuming, the risk of collision greatly influences the mission success rate. In this context, this paper assesses the collision risk during deorbit trajectories with low thrust. Furthermore, parametric studies for the relationship between the re-entry time and the risk of collision are performed.
