Galileo High Accuracy Service (HAS) Performance Analysis Report
2024.04.29
Precise Point Positioning (PPP) technology can achieve high-precision positioning anywhere in the world. Compared with real-time dynamic differential positioning technology, PPP technology does not require a dense reference station network, but its accuracy relies on high-precision satellite orbits and clock deviation products. The Galileo satellite navigation system is a global navigation satellite system (GNSS) jointly developed by the European Union (EU) and the European Space Agency (ESA). Among them, the High Accuracy Service (HAS) issued by the Galileo satellite navigation system can provide real-time precision single point positioning (PPP) services worldwide. Since the birth of the Galileo satellite navigation system, many domestic and foreign scholars and experts have conducted a large amount of research on satellite signal modes, satellite data quality, navigation algorithms, positioning performance evaluation and other aspects based on simulated data or measured data.
