Inertial Frame Relative Motion Equations

Author: Tianjiang Shuo Website: https://cislunarspace.cn

Definition

Equations of relative motion expressed in an inertial coordinate frame. Unlike rotating-frame formulations such as the CW equations, the inertial-frame description more directly reflects the actual dynamical behavior in a multi-body environment, making it suitable for analyzing long-term formation evolution near libration points.

Application Value

This dynamic method or concept has significant application value in cislunar space mission analysis, helping to understand and optimize spacecraft motion characteristics.
