Perilune Database

Author: Tianjiang Shuo

Definition

A trajectory segment database constructed through Monte Carlo trajectory shooting, storing the spacecraft state vectors at perilune arrival, velocity changes before and after impulse application, and characteristic information such as perilune altitude and velocity direction. Database entries are matched by conditions including perilune altitude, velocity direction, and distance from the Earth-Moon orbital plane, serving as the core data source for trajectory patching.

Application Value

The Perilune Database stores extensive Monte Carlo trajectory shooting results. During spacecraft trajectory planning, state vectors under matching conditions can be directly queried to quickly obtain key parameters such as perilune altitude and velocity direction, enabling efficient trajectory segment patching.
