In July 2025, researchers from Gdynia Maritime University and the German Aerospace Center (DLR) traced nearly daily GPS signal disruptions, including both jamming and spoofing, across the Baltic Sea region. These interferences originate from Russian military electronic warfare units based in Kaliningrad’s Okunevo antenna complex and the Baltiysk area. These GPS interferences, traced within approximately one kilometer of known Russian electronic warfare installations, are viewed as deliberate tactics in hybrid warfare, undermining civil navigation , including maritime, and prompting regional efforts toward resilient alternatives like R-Mode radio navigation.
