  • •MCA warns of increasing GNSS interference affecting maritime operations.
  • •Daily GPS jamming incidents average over 5,131, impacting 124,000 vessels.
  • •A seven-day GNSS outage could cost the UK maritime economy £1.5 billion.

The UK Maritime and Coastguard Agency (MCA) issued Marine Guidance Note 719 on 1 October 2026, urging maritime stakeholders to prepare for potential disruptions to GPS due to increasing GNSS interference, particularly in the Baltic, Black Sea, Middle East Gulf, and parts of East Asia. The guidance highlights risks of jamming and spoofing, which can compromise critical systems like ECDIS, AIS, and GMDSS. Recent data indicates an average of 5,131 GPS jamming incidents daily, affecting over 124,000 vessels. A seven-day GNSS outage could cost the UK maritime economy £1.5 billion, with significant impacts on port operations. The MCA recommends crews practice navigation without GPS and develop contingency plans. The UK government is working on an Enhanced Long-Range (eLoran) program to provide a terrestrial backup, with initial capabilities expected by 2028 and full operational capability by 2030.
