GNSS radio reference station is a ground-based facility that combines the Global Navigation Satellite System (GNSS) with radio communication technology. It uses a high-precision GNSS receiver to determine its exact location and transmits real-time data—including position information, satellite signal observations, and error correction data—to users via radio communication links. This setup provides users with accurate positioning benchmarks and auxiliary data, enhancing the precision and reliability of their GNSS positioning.
