Definition

A class of shape functions for low-thrust trajectory design. They describe the trajectory geometry using inverse polynomials (reciprocal forms of time polynomials), providing initial guesses for subsequent numerical optimization during the preliminary trajectory design phase.

Application Value

Inverse Polynomial Shape Function plays an important role in orbit maneuver design, analysis, and transfer planning for cislunar missions.
