When GPS fails at sea: Understanding Spoofing, Jamming, and Maritime Navigation Risk

In this CyberCast episode, host Louis Zezeran is joined by Rob Gillette (NAL Research) and Stefan Grefsgaard (SGM Technology) to unpack a growing and often misunderstood threat: GPS spoofing and jamming in the maritime domain. The conversation explores why GNSS systems are vulnerable by design, how interference manifests in real-world operations, and why this issue has become a critical concern for safety, security, and commercial shipping.Through real-world examples and testing experiences, the discussion explains the difference between jamming and spoofing, how navigation systems behave under interference, and why trust in positioning data has become a security concern. Rather than focusing on a single solution, the episode looks at broader principles such as independent verification, resilience, and operational awareness.🎧 Listen now and subscribe for more practical discussions on real-world security challenges from NEVERHACK Estonia.
