Definition

The core principle of libration point orbit station-keeping. After decomposing motion into center, stable, and unstable components via quasi-Floquet transformation, impulsive maneuvers set the unstable component to zero, preventing exponential divergence. This method does not require a pre-determined nominal orbit and can be executed at any point.

Application Value

This term has application value in the design and analysis of cislunar space missions, supporting trajectory design, mission planning, and system optimization. Researchers can analyze its physical mechanisms and engineering applicability based on specific mission requirements to advance cislunar space exploration technology.
