Floquet Strategy

Author: Tianjiang Shuo

Definition

A station-keeping strategy for libration point orbits. It computes the state transition matrix at nodal points of the nominal orbit and uses Floquet decomposition to cancel the unstable component, keeping the spacecraft near the nominal orbit. Requires a pre-determined nominal orbit and its associated state transition matrix.

Application Value

Floquet Strategy plays an important role in orbit maneuver design, analysis, and transfer planning for cislunar missions.
