Satellite radio based vehicle positioning system

摘要

A vehicle positioning system architecture according to the invention employs a satellite radio system ("SRS") to deliver global positioning system ("GPS") correction data to vehicles. A vehicle having a compatible onboard positioning system receives standard GPS data from GPS satellites, along with SRS signals from SRS satellites and/or SRS terrestrial repeaters. The onboard vehicle positioning system corrects the GPS data with GPS correction data received via the SRS signals.
