Jammed! GPS Signals Easy To Block

The signals that tell us where we are and direct us to where we’re going are surprisingly easy to disrupt, according to The Economist.  GPS jammers are illegal to use in most Western countries, but cybersecurity expert Charles Curry claims they can still be had by motivated buyers:

In the right (or wrong) hands, they are potential weapons… Mr Curry worries that criminals or terrorists could knock out GPS for an entire city or shipping lane anywhere in a flash. Even without North Korean-sized contraptions, the jamming can be substantial. Suitcase-sized devices on sale on the internet claim a range of 300-1,000 metres.

(In American distances, that’s over half a mile.)

Combined with ongoing developments in robot exoskeletons, comic book supervillains are yet another step closer to reality.
