Abstract: Disclosed is a system for providing multiple location corrections streams to receiving devices using a high-power transmitter, such as a television station, for correcting errors in the determination of a location of a receiving device based on satellite data. The system enables a receiving device to select one of the location corrections streams for processing without any upstream/return path link to the television station or processing server. The system includes multiple base stations distributed across a geographic area that each transmit location corrections stream to the processing server, which combines them to a composite corrections stream and transmits it to television stations for further broadcasting. A receiving device within a coverage area of a television station receives the composite corrections stream, selects a corrections stream corresponding to a base station closest to the receiving device, and uses the selected corrections stream to correct the location determined using satellite data.
