Space-Based GNSS Interference Source Identified as Russian Early Warning Satellites (arxiv.org)

• Russian Molniya satellites identified as GNSS interference source
• Interference events spanning Europe, Greenland, and Canada since 2019
• Detection based on terrestrial reference station data from 2019 to 2026

"A new scientific paper identifies a constellation of Russian early warning satellites in Molniya orbits as the source of wide-area GNSS interference events over Europe, Greenland, and Canada since 2019. The analysis uses data from terrestrial reference stations between 2019 and 2026."
