HOW TO FOOL A GPS - TED TALK BY TODD HUMPHREYS

Since May 2000, GPS accuracy has been a part of every civilian’s life and was the trigger for GPS-tech innovation. Unfortunately, the endless possibilities that the high accuracy provided can be used to harm and threaten.

The need to feel safe from GPS tracking has led to the increasing use of GPS jammers. Using these jammers is against the law, and the collateral effect of their signal can be dangerous and even deadly to the devices and infrastructures surrounding us, who are almost relying on GPS.

More elaborate and less commonly used for by individuals, is GPS spoofing – creating fake timing and positioning. In the case of spoofing, Civil GPS is extremely vulnerable to spoofing attacks, since its signal is not encrypted, and there is a clear proof that there is a technology capable of spoofing.
The conflict between privacy and safe GPS use is yet to be reconciled, and rises more and more questions.

Todd Humphreys, Director of the Radionavigation Laboratory in the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin, specializes in GNSS, its vulnerabilities, how to protect it and what the future holds for it.
