Definition
The state where two orbits intersect with tangential and similar velocity directions at the intersection point. Lyapunov orbits and DROs have tangential intersection points at y=0, ẋ=0, minimizing velocity insertion errors at those points.
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。
