Definition

A staged LPO constellation optimization method: the first step rapidly screens candidate families using orbit family as the parameter; the second step selects the optimal configuration from candidate families using orbit amplitude as the parameter. By using prior information to narrow the optimization scope and combining genetic algorithms (GA) with Tabu search (TS) for global exploration and local refinement, this method significantly improves optimization efficiency.

Application Value

两步优化算法先进行全局搜索再进行局部优化，是求解复杂轨道优化问题的有效策略。
