Lorentz Contraction

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

A relativistic effect in GCRS-BCRS coordinate transformation arising from the different time definitions of the two frames, causing coordinate vectors to shrink along the Earth's orbital velocity direction. For cislunar libration point targets, this effect is on the order of several meters.

Application Value

This concept is essential for understanding motion characteristics in spacecraft dynamics analysis and design, and plays a vital role in mission success.
