- This paper identifies a space-based GNSS interference source causing wide-area interference events across Europe, Greenland, and Canada since 2019.
- It introduces a detection framework using received power and details the spatial, temporal, and spectral patterns of the events.
- Using received-power and time-difference-of-arrival measurements, the source is confidently identified as Russian early warning satellites in Molniya orbits.
