Definition

A dynamical model approximating the Sun-Earth-Moon-spacecraft four-body system where Earth and Moon revolve in circular orbits around their barycenter, which in turn orbits the Sun; all motions are coplanar with constant angular velocity. Compared to CRTBP, it incorporates solar gravitational perturbation.

Application Value

This concept has important application value in cislunar space research and mission design.
