Definition
A satellite constellation deployed on typical cislunar orbits such as DRO and NRHO, serving dual functions of navigation/positioning and space-based tracking stations. The paper uses a four-satellite constellation of 2 DRO and 2 NRHO satellites as space-based stations for cataloguing orbit determination.
Application Value
The four-satellite constellation (2 DRO + 2 NRHO) serves simultaneously as a navigation signal source and tracking station, significantly improving the cataloguing and orbit determination accuracy for cislunar targets. Compared with ground-based stations, space-based stations offer better visibility of distant targets, making them important infrastructure for future cislunar situation awareness.
