<!--!introduction!--> Our modern society heavily relies on the Global Navigation Satellite System (GNSS) applications that utilize trans-ionospheric radio waves. However, these applications can be highly affected by ionospheric scintillations. The GNSS service can be particularly disturbed during severe geomagnetic storms. In this study, we investigate ionospheric scintillations during major geomagnetic storms (minimum Dst < -100 nT). We make use of a network of 11 GNSS scintillation receivers of type Septentrio PolaRxS, which is operated by the Norwegian Mapping Authority. The network covers a wide latitudinal range, from the polar cap to auroral and subauroral regions. Thus, it can capture the scintillation effect associated with variable phenomena at high latitudes, such as polar cap patches, plasma blobs, auroral precipitation, and ionospheric trough. Most previous studies have focused on geomagnetic conditions that are less active and mostly only report significant phase scintillations of GNSS ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
