Özet
The study investigates ionospheric scintillations over the high-latitude Svalbard archipelago, Norway region using multi-constellation GNSS (GPS, GLONASS, Galileo, and BeiDou) observations during the period from 2022 to 2024. To analyze the impact of ionospheric scintillation characteristics over high-latitudes, we investigated the GNSS observations at the WUTH station, which is located at the Svalbard Archipelago, Norway. Our results confirm the well-established dependency of high-latitude scintillation on solar and seasonal activity, but importantly extend this understanding through a multi-constellation comparison at the WUTH during the rising phase of Solar Cycle 25. The analysis highlights subtle but systematic differences among GPS, GLONASS, Galileo, and BeiDou responses, providing practical insight into the robustness of multi-constellation monitoring under polar ionospheric disturbances. The seasonal variability of amplitude scintillation occurrence probability was calculated by normalizing the number of scintillation events by the total number of observations for each year. The results show that the GPS intense scintillations are most prominent during the summer solstices of 2023 and 2024, with a smaller peak observed during the winter solstice of 2022. GLONASS has intense and moderate scintillations concentrated in the winter seasons of 2023 and 2024, whereas weak scintillations predominantly appear in the summer of 2024. A similar pattern is observed in the Galileo and BeiDou constellations. The amplitude scintillation index (S4 ) correlation coefficient with solar and geomagnetic indices for each constellation is examined. Overall, the correlation coefficient between F10.7 and the S4 occurrence rate is low to moderate for all selected constellations, manifesting a higher correlation with GLONASS and Galileo. These results provide new, site-specific insight into constellation-dependent amplitude scintillation behavior at high latitudes and its implications for multi-GNSS monitoring and positioning robustness in polar regions.
