Summary
GNSS interference, typically concentrated in and around military conflict zones, is increasingly affecting commercial shipping routes, with serious implications for navigational safety. Recently the shipping industry has seen multiple incidents of navigational confusion, including a case in May 2025 in which a container ship allegedly ran aground in the Red Sea after being subjected to GPS spoofing.
On 24 March 2025, the growing threat of GNSS jamming and spoofing to commercial shipping was the focus of a BIMCO webinar. The webinar featured representatives from the marine tech industry explaining a new GNSS interference risk management concept and the associated technology, and a representative from the shipowner side sharing experiences with a shipowner’s practical implementation of the solution in question.
The webinar delved into how GNSS interference challenge has sparked innovation in the maritime tech industry, and solutions are now emerging which draw on signals from low earth-orbit communications satellites thereby reducing the risk of jamming due to higher signal strength.
The webinar concluded with a Q&A session covering accuracy, integration with existing bridge systems, cybersecurity, and regulatory considerations.
GPS jamming and spoofing is a growing threat with real safety and security consequences for ships.
