Navy Accidentally Jammed GPS System in San Diego
GPS system signals are everywhere and the technology is used for literally thousands of applications, not just navigating drivers on the road. GPS technology is used to land airplanes, control financial services such as ATMs and stock trading, navigate ships and cargo, synchronize data on wireless networks, manage loads on power grids, etc.
Jamming the GPS system can wreak havoc on society in literally thousands of ways. Ways many people are not even aware of.
According to an article recently printed in the New Scientist, a British magazine, a global positioning system outage happened because the Navy accidentally jammed GPS signals in downtown San Diego in 2007.
New Scientist magazine wrote in its March 2011 edition: “It was just after midday in San Diego, California, when the disruption started. In the tower at the airport, air-traffic controllers peered at their monitors only to find that their system for tracking incoming planes was malfunctioning. At the Naval Medical Center, emergency pagers used for summoning doctors stopped working. Chaos threatened in the busy harbour, too, after the traffic-management system used for guiding boats failed. On the streets, people reaching for their cellphones found they had no signal and bank customers trying to withdraw cash from local ATMs were refused.”
The problem with the article in New Scientist is that most of what it reported wasn’t true. Although the Navy did admit to accidentally jamming GPS signals in San Diego in 2007, the outcome wasn’t anywhere nearly as catastrophic as the magazine made it out to be.
