Two-Impulse Rendezvous

Author: Tianjiang Shuo

Definition

An orbital rendezvous accomplished by applying exactly one velocity increment at departure and one at arrival. No thrust is applied during the coast phase between the two impulses, so the spacecraft follows a natural Keplerian arc under gravity alone. This mode is structurally simple and directly compatible with Lambert problem formulations, making it the canonical scenario for Hohmann-type transfers between coplanar circular orbits.

Application Value

The 双脉冲交会 concept is applied in cislunar space research, providing technical support or analytical methods for lunar exploration missions.
