Non-GPS navigation introduced

BAE Systems has introduced its 'Navigation via Signals of Opportunity' (NAVSOP) system, which is independent of GPS.

The new system claims to be able to calculate its position by making use of the hundreds of different signals that are all around us - not an entirely new concept, but one being taken to greater capability.

BAE explains that NAVSOP is resistant to hostile interference such as jamming and spoofing, and can learn from unidentified signals to build an ever more accurate and reliable fix - indeed, even signals from GPS jammers can be exploited.

The infrastructure for NAVSOP already exists - the hardware behind the system is already in place. And it can be integrated into existing positioning devices to provide superior performance to stand-alone GPS.

A major advantage claimed for the system is its ability to function in places where GPS is unavailable, such as dense urban areas and deep inside buildings. It is also able to work in the most remote parts of the world, such as the Arctic, by using signals that include low-earth-orbit (LEO) satellites.

NAVSOP is being proposed for a wide range of potential military applications, from aiding the military in remote or dense urban areas to providing improved security for UAVs.

The research is apparently generating interest in both defence and civilian domains, where its uses could include helping fire and rescue services in smoke filled buildings and enhancing the safety of lone workers and security staff.
