Using GPS to hijack ships and crash drones

Satellite navigation systems such as GPS, the Global Positioning System that provides location information for our smartphones and navigation systems, have become a very useful tool in our daily lives. While today we mostly rely on the US GPS, built in the 1970s, even Europe, after many delays, will finally have its own system (Russia already has their own called GLONASS).

However, the more we rely on GPS navigation, not only for posting our location on Facebook but for car, plane and ship navigation, the more incidents happen, which show the vulnerability of the technology. In 2012 a drone by the Austrian manufacturer Schiebel crashed in South Korea, killing an engineer. It was believed back then that this happened in connection with GPS signal jamming by North Korea, which caused navigation problems in the past. This adds to other drone vulnerabilities discovered in recent years, such as unencrypted video feeds.

Now, students of the University of Texas showed in an experiment how they could hijack a Yacht using GPS spoofing without any crew member noticing (similar to what Iran claimed to have done in 2011). They achieved this by creating a fake GPS signal and slowly increasing its signal strength until the ships automatic navigation system completely relied on this signal. Then, they slowly changed the signal to make the Yacht believe it is off course and to correct for it. Here is a description about the method:
