Nihil nova. Been there. This exact technology (plus some very
interesting extras) called localizers is also described en detail in
Vernor Vinge's A Deepness In The Sky, a work of science
fiction. Essentially, these gadgets create a 3d meshwork of mutual TOF
triangulation, using digital pulse radio.
If you could make EM-pulse pumpable fully integrated (spherical Si?)
gadgets like http://xent.ics.uci.edu/FoRK-archive/nov99/0555.html
and fabricate them for few bucks a piece, or less, you're in business.
Otherwise, the problem will be, as so often, juice.
