Definition
A station-keeping strategy based on the eigenspectrum of the linearized dynamics near libration point orbits. By decomposing motion into unstable, stable, and center modes, the method selectively damps the unstable component to maintain the spacecraft near the target orbit with minimal fuel expenditure.
