Definition
A technique that pre-computes and stores approximate analytical representations of manifold tube volumes in discrete phase-space cells, avoiding expensive numerical propagation of individual manifold arcs. When a trajectory enters a cell, the stored relationships quickly estimate the maneuver required to reach a target halo orbit, reducing the search cost from O(N integrations) to O(1) lookups.
Application Value
在单元估计法的分析中,可用于轨道传播和机动设计,帮助工程师评估航天器在不同动力学环境下的运动特性 该概念为地月空间任务设计提供了理论基础,尤其在平动点轨道设计和低能转移分析中具有重要应用价值 利用单元估计法进行轨迹优化,可以有效降低任务燃料消耗,提高任务经济效益 在任务设计中,单元估计法的分析有助于理解航天器在复杂引力场中的行为,指导轨道保持策略的制定
