Stockholm, 28 January 2026Coastal states around the Baltic Sea and the North Sea, joined by Iceland, have issued a joint warning to the international maritime community over growing threats to navigation safety caused by GNSS interference and AIS manipulation. Dear Members of the International Maritime Community,Modern maritime transport is fundamentally built on the reliability of satellite-based navigation. Spoofing or falsifying AIS data undermines maritime safety and security, increases the risk of accidents, and severely hampers rescue operations. We therefore call upon the international maritime community and national authorities to:Recognize GNSS interference and AIS manipulation as threats to maritime safety and security. Maintaining trust in maritime navigation requires more than technology – it demands responsibility, transparency, and decisive action.
