Normalized Parameter

Definition

Parameters that render physical quantities dimensionless. In the PBCR4BP model, distance, velocity, and time are normalized using the sum of Earth-Moon masses, the mean Earth-Moon distance, and the mean angular velocity of Earth-Moon rotation about their barycenter as reference quantities, simplifying dynamical equations and improving numerical efficiency.

Application Value

This concept provides fundamental support in cislunar space research and mission design. In practical applications, the appropriate analysis method should be selected based on specific mission scenarios and constraints.
