GEO Satellites Assisted Multi-Orbit Positioning Network Using RSMA and GDOP
Year: 2025
Type: conference-paper
Abstract: With the widespread application of the global navigation satellite system in geographic information services, improving positioning accuracy in complex environments has attracted significant attention. Traditional navigation constellations composed of medium Earth orbit satellites often suffer from insufficient satellite visibility and poor geometric distribution in urban canyons and mountainous areas, leading to elevated geometric dilution of precision (GDOP) values that degrade user positioning performance. While multi-orbit fusion positioning techniques have seen growing interest in recent years, existing approaches typically treat geostationary Earth orbit (GEO) satellites merely as signal relay nodes, failing to fully leverage their potential as active navigation members in joint positioning. To address these challenges, this paper proposes a satellite network incorporating GEO satellites into joint positioning which enhances GDOP. Simulation results demonstrate that this network improves positioning performance in constrained environments.
