Blog Editor’s Note:

The Danish firm Risk Intelligence recently made its September 2018 report on government interference with GPS and its impact on shipping available on its website. The report cites numerous areas around the globe subject to chronic GPS jamming and spoofing.

 “Government sponsored GPS interference as a risk to commercial shipping,” identifies high levels of activity in some of the world’s busy shipping routes.

Impacted systems aboard commercial vessels include GPS, ECDIS, AIS, VSAT, Fleet Broadband, VHF, LRIT, and Inmarsat C.

The report suggests several procedural and hardware/software mitigations to counter these threats.

Copies of the report are available at the Risk Intelligence website at
