Vertical Lyapunov Orbit

Author: Tianjiang Shuo Website: https://cislunarspace.cn

Definition

Family of periodic orbits arising from the vertical center of the linearized equations at a collinear libration point; frequencies relate to both the planar and vertical center frequencies.

Application Value

This concept plays a key role in trajectory transfer design, helping evaluate transfer costs and flight time to provide quantitative basis for mission trade studies. Combined with global search algorithms, multiple solution families and Pareto frontiers can be identified to guide orbital design decisions.
