マルチGNSSによる測位特性評価

Abstract

This paper shows the positioning accuracy by the multi-GNSS (Global Navigation Satellite Systems). In the field of the satellite positioning systems, the GPS (Global Positioning Systems) , which is maintained by the United States government, is very famous in the world. Recently, the GLONASS (Global Navigation Satellite System:Russia), the Galileo (EU) , the Baidu (China) and the QZSS (Quasi Zenith Satellite System: Japan) are running and are freely accessible by anyone with a receiver. The GNSS is defined as space-based positioning system environment using mutually these satellite systems. However, it has not been clearly indicated that how positioning accuracy using the multi-GNSS are resulted because there are not many receivers of the GNSS for consumers in the world. In this research, the signal information from the multi-GNSS was received by being applied in JAXA (Japan Aerospace Exploration Agency)’s QZSS Experiment. The results from processing the signal information showed that the GNSS combination of the GPS and the QZSS has the highest positioning accuracy.
