Solar Radio Burst Events on 6 September 2017 and Its Impact on GNSS Signal Frequencies
Original language description
During the intense solar radio bursts on 6 September 2017, Global Navigation Satellite Systems (GNSS) signal interferences were observed at ground stations in the European longitude sector from 20 degrees N to 70 degrees N for all GNSS satellites in view including GPS, GLONASS, and Galileo. The solar radio noise reduced the signal-to-noise ratio with clear frequency dependence. The impact of the radio burst has been found at L2 and L5 frequencies, but not at L1 frequency. The ground observation of the solar radio spectrum between 1.0 and 2.0 GHz corresponds well to such frequency dependence. The maximum signal-to-noise ratio reduction of -10 dB was found when the solar radio flux was pulsating around 2,000 solar flux unit level. Precise point positioning results show that accuracy is reduced with stronger deviation for dual-frequency solutions than for single-frequency solutions based on L1 signal only. The positioning error refers rather to the solar extreme ultraviolet flare than to solar radio interferences. The results presented here are a clear indication of frequency-dependent GNSS performance degradation during strong space weather events.
