Full-Ephemeris Model

Author: Tianjiang Shuo

Definition

A high-fidelity dynamical model incorporating real ephemeris data (positions, velocities) of multiple celestial bodies, accounting for solar gravitational perturbations and non-spherical gravity effects. Compared to the idealized assumptions of the circular restricted three-body problem, it is closer to the real flight environment. Orbit design typically begins in the three-body model and transitions to the full-ephemeris model for verification and refinement.

Application Value

This concept plays an important role in cislunar space mission design and orbital dynamics analysis.
