Definition
The full dynamical model including gravitational effects of the sun, Earth, and moon. Compared to the Earth-moon CRTBP, it introduces the sun as a fourth-body perturbation source, producing transfer trajectories that exploit sun-Earth libration point dynamics or solar gravity to reduce delta-V.
Application Value
在航天器动力学建模中，需要准确描述引力场、摄动力和坐标系变换。该概念是进行轨道力学分析、姿态控制和任务设计的基础。
