GNSS Frequency Availability Analysis
Keywords:
BeiDou, Galileo, GLONASS, GPSAbstract
In this study, three RINEX-3 daily observation data in 2021 were investigated in terms of the frequency availability of Global Navigation Satellite System (GNSS). All available frequencies in the RINEX-3 header were chosen to investigate for GPS, GLONASS, Galileo, and BDS data. The results showed that average frequency availability can be varied significantly among the frequencies and GNSSs. Availability of Galileo frequencies were found higher than the other GNSSs among the examined RINEX files.
