ATSC 3.0 Usable for Enhancing GPS, Says BitPath

ATSC 3.0 consortium BitPath and Sinclair-affiliated One Media and Cast.Era demoed possible use of 3.0 to enhance GPS accuracy, BitPath said. Called “enhanced GPS,” this allows positional accuracy within centimeters, BitPath said. “Using the high-power data transmission capacity of terrestrial broadcast stations, the reliability of eGPS positioning can be broadcast to an unlimited number of vehicles inside of the range of a licensed broadcast television station.” The technology allows “near real-time broadcasting of live images” that could provide additional information to first responders and enhance newsgathering, it said.
