Continuation Procedure

Definition

A numerical method that maps objects from one dynamical model to their counterparts in another by gradually varying a parameter. For libration points, continuation from CR3BP to B4BP uses a fraction of the solar mass (for EM libration points) or a fraction of the Earth-Moon distance (for Sun-Barycenter points) as the parameter; each step uses the current solution as the initial guess solved by parallel shooting and differential correction.

Application Value

用于分析航天器在复杂引力场中的运动特性 该概念为地月空间任务设计提供了重要的理论基础 在实际工程中可用于轨道设计、任务规划或控制系统分析。
