Not just affecting your car 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 jamers can be used to defeat vehicle tracking products — but end up causing a moving cloud of chaos. Next wave of anti-GPS devices include GPS spoofers to trick or confuse nearby devices — scary.
