Definition

Time-dependent trajectories in high-fidelity ephemeris models that mimic the behavior of CRTBP invariant manifolds. Computed by propagating the state transition matrix over multiple revolutions of a quasi-periodic orbit and extracting eigenvectors, since strict invariant manifolds do not exist in non-autonomous ephemeris models.

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.
