Jamming and Spoofing of Global Navigation Satellite Systems (GNSS): Are you ready?

Global Navigational Satellite Systems (GNSS) are powerful aids that, when used correctly, enhance navigational safety and reduce bridge workload. However, while GNSS data feeding ECDIS has transformed navigation, it has also introduced risks. Overreliance on satellite positioning can erode watch officers’ skills, experience, and ability to navigate if GNSS signals are lost or compromised. This dependency leaves the bridge vulnerable, particularly as man-made GNSS interference, such as jamming and spoofing, becomes increasingly common.

Shipping companies must act now by updating SMS procedures, training bridge teams, and preparing crews to operate safely in GNSS-compromised environments.

Alpha Marine Consulting assists companies in enhancing GNSS resilience by conducting risk assessments, developing procedures,
and integrating these measures into your Safety Management System.
