Popular Science: Television Signals Plug the Holes in GPS
Popular Science writes about a GPS system that, if-it-could-possibly-work-but-I’m-not-that-smart-so-I-can’t-see-how, could go quite a long way toward leveraging the power of GPS mapping to applications that just couldn’t use it before. I’m thinking of analyses of patrons through a library space, primarily, but it could just as easily look at shoppers through retail space. But TV signals? I guess. It feels a little like the time I tried to make a hand-powered “tree-felling machine” with a spare chain and a dilapidated, upside-down Huffy. (Not really).

GPS is indespensable, but reception is spotty indoors and in urban areas. A new system that uses digital television signals should clear the way for anytime, anywhere positioning
