Russian Molniya Satellites Identified Behind European GNSS Interference Crisis

Researchers have traced widespread GPS/GNSS disruptions affecting Europe, Greenland, and Canada since 2019 to Russian Molniya orbit early-warning satellites. Space-based interference sources pose a more significant threat than terrestrial jamming due to their vast geographic reach and potential for escalation. This research underscores the critical need for advanced GNSS interference detection and geolocation techniques in an increasingly contested navigation environment.
