"The war in Iran has dominated headlines with reports of airstrikes and
escalating military activity. But beyond the immediate devastation, the
conflict has also illuminated a quieter and rapidly growing danger: the
vulnerability of ships, and the people who operate them, to disruption of their
navigation systems.
Modern shipping depends heavily on GPS satellite navigation. When those signals
are disrupted or manipulated, ships can suddenly appear to their navigators and
to other ships to be somewhere they are not. In some cases, vessels have been
shown jumping across maps, drifting miles inland or appearing to circle in
impossible patterns. The risk is even higher in war zones, where ships could be
misdirected into harm’s way.
As a cybersecurity researcher studying critical infrastructure and maritime
systems, I investigate how digital threats affect ships and the people who
operate them.
To understand the threat from GPS disruptions, it helps to first understand how
GPS works. GPS systems determine location using signals from satellites
orbiting Earth. A receiver calculates its position by measuring how long those
signals take to arrive. Because those signals are extremely weak by the time
they reach Earth, they are relatively easy to disrupt."
