Double-Pulse Orbit Transfer

Author: Tianjiang Shuo

Definition

An orbit transfer method that applies one velocity impulse at each of the departure and arrival points, the classic application of Lambert's problem. The first impulse departs the initial orbit onto a transfer trajectory; the second inserts the spacecraft into the target orbit. Compared with continuous-thrust guidance, double-pulse transfer is simpler to implement but demands higher instantaneous thrust, serving as a fundamental scheme for long-range orbital maneuvers.

Application Value

This term has application value in the design and analysis of cislunar space missions, supporting trajectory design, mission planning, and system optimization. Researchers can analyze its physical mechanisms and engineering applicability based on specific mission requirements to advance cislunar space exploration technology.
