In the context of future human spaceflight exploration missions, Rendezvous and Docking (RVD) activities are critical for the assembly and maintenance of cislunar structures. The scope of this research is to investigate the specifics of orbits of interest for RVD in the cislunar realm and to propose novel strategies to safely perform these kinds of operations. This paper focuses on far rendezvous approaches and passively safe drift trajectories in the Ephemeris model. The goal is to exhibit phasing orbit requirements to ensure a safe far approach. Ephemeris representations of Near Rectilinear Halo Orbits (NRHOs) were derived using multiple-shooting and adaptive receding-horizon targeting algorithms. Simulations showed significant drift and overlapping properties for phasing and target orbits of interest, motivating the search for safe natural drift trajectories and using impact prediction strategies.

近直线 Halo 轨道中的地月会合设计

在未来载人航天探索任务的背景下，交会对接 (RVD) 活动对于地月结构的组装和维护至关重要。这项研究的范围是调查 RVD 在地月领域感兴趣的轨道的细节，并提出新的策略来安全地执行这些操作。本文重点介绍 Ephemeris 模型中的远交会方法和被动安全漂移轨迹。目标是展示定相轨道要求，以确保安全的远距离进近。近直线晕轨道 (NRHO) 的星历表示是使用多次射击和自适应后退水平定位算法得出的。模拟显示了重要的定相和目标轨道的显着漂移和重叠特性，
