But despite the dangers, there are mitigations. Indeed, few technologies have reshaped maritime navigation as completely as satellite positioning. Over the past three decades Global Navigation Satellite Systems (GNSS) have moved from specialist navigation tools to the backbone of modern maritime operations. They now support everything from deep sea route planning to dynamic positioning and complex port approaches.

That success has encouraged a widespread assumption across the sector that satellite signals will always be available and reliable. Recent events suggest that assumption is becoming harder to defend. And this is where APNT enters the equation, providing greater confidence in vessel positioning and supporting more informed risk…
