Modern maritime navigation depends on trusted Positioning, Navigation, and Timing (PNT) information provided by GNSS and integrated bridge systems. Technologies such as ECDIS, AIS, radar, and track-control systems improve navigational awareness but also create dependencies on digital information.
This episode examines how GNSS spoofing can compromise navigation integrity without damaging equipment or disrupting communications. Students explore how inaccurate position information can influence operational decision-making, how information integrity failures can become navigational hazards, and why resilience requires independent verification, sensor diversity, and human oversight.
Key Security-Informed Safety Lesson:
Cyber events become safety hazards when compromised information influences operational decisions and physical system behaviour.
