Abstract:	The main objective of this study was to evaluate the performance of a dual-frequency multi-constellation (DFMC) satellite-based augmentation system (SBAS) broadcast from the Japanese Quasi-Zenith Satellite System (QZSS) in the Arctic and high-latitude regions. We installed a global navigation satellite system (GNSS) antenna and receiver on the roof of the Kjemibygningen (chemistry building) at the University of Oslo, Norway, on February 24, 2021, and conducted experiments continuously until March 17, 2021. We found that the QZSS-based DFMC SBAS achieved a system availability of 84.68% for localizer performance with vertical guidance when the horizontal and vertical alert limits were set to 40 and 50 m, respectively. This result is below the performance of QZSS-based DFMC SBAS in Japan. However, our analysis shows that adding three or more QZSS reference stations in Europe will enable DFMC SBAS from QZSS to reach 100% availability.
