Satellite-Free Navigation Systems 3 to 5 Years Away: Report

UK scientists are reportedly developing a navigation system that does not rely on satellites. And, according to GPS Daily, the technology, known as 'quantum positioning', could be available to the military within five years.

The report suggests that the new navigation system will initially serve in submarines, as the technology has the advantage of working underwater where current GPS tech does not.

Eventually, the technology behind it will find its way to smart phones, cars and aftermarket navigation devices for use by the general public.
