Dual Navigation Satellite Scheme

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

A constellation configuration that deploys two navigation satellites on the same halo orbit with initial phases 180 degrees apart. It addresses the insufficient orbit determination accuracy for cislunar transfer trajectories with a single halo navigation satellite, improving CTT orbit determination precision by at least a factor of 2 through additional observations.

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.
