Jul 3, 2012 gps navigation
A new system have been developed to protect military vehicles from GPS jamming by using already existing radio waves to locate rather than relying on GPS satellite signals. The system uses cell phone, Wifi, and TV signals to locate a person or a vehicle but can even use GPS jamming signals to correctly get a position fix.
The system is developed by BAE Systems and it intends to keep military drones safe from GPS spoofing attacks which we recently mentioned here on Navigadget.
Known as NAVSOP, this technology scavenges radio signals from the air and can work indoors or even underground where wimpy GPS satellite signals can’t reach. This technology could replace GPS in the future.
