Super-Geostationary Transfer Orbit

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

An elliptic transfer orbit with an apogee far beyond geosynchronous altitude, typically several times the GEO radius. In cislunar missions, sGTO serves as a departure orbit for low-thrust transfers, where its high apogee approaches the boundary of Earth's gravitational dominance, facilitating low-energy Earth-Moon transfers via invariant manifolds.

Application Value

This term has significant practical applications in cislunar mission planning and execution.
