$30 GPS Jammer Can Wreak Havok

An anonymous reader writes "A simple $30 GPS jammer made in China can ruin your day. It doesn't just affect your car's navigation — ATM machines, cell phone towers, plane, boat, train navigation systems all depend upon GPS signals that are easily blocked. These devices fail badly — with no redundancy. These jammers can be used to defeat vehicle tracking products — but end up causing a moving cloud of chaos. The next wave of anti-GPS devices include GPS spoofers to trick or confuse nearby devices."

I gave my wife a GPS so she can yell at it instead of me when she's lost.

And the doctor with his phone discretely on vibrate, who gets called to an emergency in the middle of the movie?

No use calling him, apparently he doesn't know the way to the hospital.
