Definition

A satellite constellation deployed around libration point orbits in the Earth-Moon system to provide navigation support for deep space probes. It exploits the spatial uniqueness and dynamical properties of libration points, achieving autonomous orbit determination through inter-satellite ranging to bridge the coverage gap of Earth-based GNSS for cislunar and beyond-lunar space.

Application Value

This term在cislunar space missions中has important application value. In orbit design, it can be used foroptimizing transfer trajectories, reducing mission fuel consumption. In attitude control and dynamics analysis, it helps understandthe motion characteristics of spacecraft in complex gravitational fields, providing theoretical support for mission planning. In navigation and orbit determination, methods based on this termcan improve orbit prediction accuracy, supporting the development of autonomous navigation algorithms.
