为月球轨道交会设计安全高效的凸优化导航方案。
Passively Safe Convex Guidance for Cislunar Rendezvous and Proximity Operations
- 用凸规划实现无需人工干预的轨道交会与逼近操作。
- 在误差和不确定性下验证了90%以上任务成功率。
- 适用于航天器自主导航，已用于NASA CAPSTONE任务。
本文提出了一种纯凸规划方法，用于地月轨道中的被动安全脉冲式交会与近轨操作。针对机动执行误差和导航不确定性，设计并验证了接近、抵达及中止等各类机动策略，适配自主场景下的高效星载执行。该方法已成为计划在南向9:2同步近直线晕轨道执行自主交会与近轨操作的NASA CAPSTONE 02任务的基准星载引导程序。采用预期相对导航传感器组合与测量频率，通过高保真闭环蒙特卡洛仿真验证了机动设计性能。
原文摘要 · Abstract (English)
This paper presents purely convex programs for passively safe impulsive rendezvous and proximity operations in cislunar orbits. Approach, arrival, and abort maneuvers are all designed and validated in the context of maneuver execution error and navigation uncertainty, and formulated for efficient onboard execution in the autonomous scenario. The outlined methods form the baseline onboard guidance routines for NASA's CAPSTONE 02 mission planned to demonstrate autonomous rendezvous and proximity operations capabilities in the southern 9:2 synodic near rectilinear halo orbit. High fidelity closed loop Monte Carlo simulations using the planned relative navigation sensor suite and measurement cadence verify the intended maneuver design performance.
