DARPA Promoting New Tracking Methods

What are the broader implications of these new methods commercially?   What comes to mind are technologies that will be more precise and reliable inside buildings,  notably for retail applications and emergency response. .In CWorld:

" ... New types of self-contained instruments are under development that could better track position, time and direction of motion, which are critical aspects of GPS. DARPA is developing high-precision clocks, self-calibrating gyroscopes and accelerometers, and high-precision navigation instruments that can track position for long periods without relying on external sources.

DARPA is also researching new technologies that could make real-time tracking possible through a number of sources. DARPA is developing sensors that "use signals of opportunity" such as television, radio, cell towers, satellites, and even lightning, for real-time tracking. The effort, called ASPN (All Source Positioning and Navigation) alleviates issues related to fixing locations in buildings, deep foliage, underwater or underground, where GPS access can be limited ...
