Definition

A protection region concept defined in the paper for the Gateway station. Using the CR3BP periodic solution as reference, a pseudo-toroidal envelope is constructed along the orbit in the rotating frame, with radius increasing quadratically from 1000 km at periapsis to 5000 km at apoapsis, used to assess debris threat levels to the Gateway.

Application Value

在轨道设计阶段，可usingThis轨道类型构建候选轨道池，为星座部署和任务轨道选择provides参考。在轨运行时，This轨道特性可used for轨道维持策略设计，降低推进剂消耗。在轨道转移规划中，其稳定流形结构可指导低能量转移走廊的搜索。
