New Five Part Series | Episode 2: GNSS Degradation Emerges as Critical Threat to Modern Navigation – The Invisible Cyber Risk at Sea

Modern ships are more connected, more automated, and more exposed than ever before.

In this episode of the ShorelineHudson Maritime Risk Podcast, we move beyond theory and into operational reality. What happens when navigation systems don’t fail… but quietly degrade? When everything appears to be working, yet the data guiding the vessel is no longer trustworthy?

Drawing on real world developments, including escalating GNSS disruption in high-risk regions, Captain Thomas Brown and Andrew Sallay (Cequra) explore a critical and often misunderstood risk: the danger of ambiguity at sea.

From degraded positioning signals and decision-making under pressure, to the erosion of traditional seamanship skills and over-reliance on connected systems, this episode reveals how modern vessels can drift into a fragile state, without warning.

Most importantly, it examines what can be done about it.

If Episode 1 explored how fragility builds, Episode 2 shows what happens when that fragility meets reality.

A must listen for shipowners, operators, and anyone responsible for safe navigation in an increasingly complex risk environment.
