Optimized Contact Plan Design for Reflector and Phased Array Terminals in Cislunar Space Networks
Cislunar space is emerging as a critical domain for human exploration, requiring robust infrastructure to support spatial users - spacecraft with navigation and communication demands. Deploying satellites at Earth-Moon libration points offers an effective solution. This paper introduces a novel Contact Plan Design (CPD) scheme that considers two classes of cislunar transponders: Reflector Links (RL) for high-volume data transfer and Phased Array Links (PL) for fast switching and navigation services.Our approach addresses the needs of both satellites and spatial users within the Earth-Moon Libration Point Communication and Navigation Constellation (EMLP-CNC). Simulations validate the proposed scheme, demonstrating its effectiveness in serving spatial users while meeting satellite ranging and communication requirements. These findings provide essential insights for developing future Cislunar Space Infrastructures.
