Definition

A low-thrust trajectory design method. It expresses the velocity vector of a low-thrust transfer trajectory as a shape function of time or polar angle, then optimizes these functions to achieve the transfer. Applicable to transfers between Earth, Mars, asteroids, comets, and Mercury.

Application Value

This concept is essential for understanding motion characteristics in orbital design and control, and plays a vital role in mission success.
