Abstract

Space debris have become exceedingly dangerous over the years as the number of objects in orbit continues to increase. Active debris removal (ADR) missions have gained significant interest as effective means of mitigating the risk of collision between objects in space. This study focuses on developing a multi-ADR mission that utilizes controlled reentry and deorbiting. The mission comprises two spacecraft: a Servicer that brings debris to a low altitude and a Shepherd that rendezvous with the debris to later perform a controlled reentry. A preliminary mission design tool (PMDT) was developed to obtain time and fuel optimal trajectories for the proposed mission while considering the effect of J₂, drag, eclipses, and duty cycle. The PMDT can perform such trajectory optimizations for multi-debris missions with computational time under a minute. Three guidance schemes are also studied, taking the PMDT solution as a reference to validate the design methodology and provide guidance solutions to this complex mission profile.

多活动碎片清除任务的设计和指导

多年来，随着轨道上物体数量的不断增加，空间碎片变得极其危险。主动碎片清除任务作为降低空间物体碰撞风险的有效手段，引起了人们的极大兴趣。本研究的重点是开发一种利用受控再入和脱轨的多ADR任务。该任务包括两个航天器：一个是将碎片带到低空的“服务者”号，另一个是与碎片交会后进行受控再入的“牧羊人”号。开发了一个初步任务设计工具（PMDT），以获得拟议任务的时间和燃料最佳轨迹，同时考虑J2、阻力、日食和占空比的影响。PMDT可以在计算时间不到一分钟的情况下为多碎片任务执行这种轨迹优化。还研究了三种制导方案，以PMDT解决方案为参考，验证了设计方法，并为这一复杂的任务剖面提供了制导解决方案。
