Network-Aware Progressive Replacement Sequence Planning for Laser-Enhanced BeiDou Navigation Constellations
Huan Yan, Juan A. Fraire, Ziqi Yang +5
The early satellites of the third-generation BeiDou Navigation Satellite System (BDS-3) are approaching the end of their design lifetime, making progressive constellation replaceme…
Joint Contact Planning for Navigation and Communication in GNSS-Libration Point Systems
Huan Yan, Juan A. Fraire, Ziqi Yang +11
Deploying satellites at Earth-Moon Libration Points (LPs) addresses the inherent deep-space coverage gaps of low-altitude GNSS constellations. Integrating LP satellites with GNSS i…
Contact Plan Design for Cross-Linked GNSSs: An ILP Approach for Extended Applications
Huan Yan, Juan A. Fraire, Ziqi Yang +10
Global Navigation Satellite Systems (GNSS) employ inter-satellite links (ISLs) to reduce dependency on ground stations, enabling precise ranging and communication across satellites…
Optimized Contact Plan Design for Reflector and Phased Array Terminals in Cislunar Space Networks
Huan Yan, Juan A. Fraire, Ziqi Yang +8
Cislunar space is emerging as a critical domain for human exploration, requiring robust infrastructure to support spatial users-spacecraft with navigation and communication demands…
