Definition

A function derived from the Pontryagin Minimum Principle that determines optimal thrust switching. Positive value means full thrust, negative means coast, and zero means singular arc.

Application Value

This concept is fundamental to cislunar orbital mechanics and mission analysis, providing essential theoretical support for trajectory design and operational planning.
