Computerworld Malaysia - BAE Systems develops GPS alternative

Computerworld Malaysia - BAE Systems develops GPS alternative:

"The technology is being touted as a replacement for current technologies such as GPS, which relies upon a relatively weak satellite signal that is vulnerable to disruption.
Known as Navigation via Signals of Opportunity (NAVSOP), BAE Systems' new system is resistant to hostile interference such as jamming and spoofing, and can learn from signals that are initially unidentified to build a more accurate and reliable fix on its location.
NAVSOP can function in places where GPS is unable to reach, such as dense urban areas and deep inside buildings, and can work in remote parts of the world, such as the Arctic, by picking up signals that include Low-Earth-Orbit satellites and other civilian signals"
