System and method for providing aided GPS positioning via satellite digital radio system
First Claim
1. A method for providing aiding information to a satellite positioning system (“
- SPS”
) receiver comprising;
receiving a first broadcasting data signal from a data service satellite;
extracting aiding information contained in the first broadcasting data signal, where the aiding information was provided to the data service satellite from an aiding satellite positioning system server; and
sending the aiding information to the SPS receiver to aid the SPS receiver in obtaining its location from the satellite positioning system.

Abstract
A system and method for providing aiding information to a satellite positioning system (“SPS”) receiver. A digital satellite radio system satellite receives aiding information communicated from a positioning system. The digital satellite radio system broadcasts the aiding information in the data signals it broadcasts to its subscribers. The subscribers receive the aiding information at satellite radio receivers and communicate the aiding information to the SPS receiver. The data signals may also be communicated to terrestrial repeaters for re-broadcast at a higher power. The terrestrial repeaters may input a transmitter identifier to permit the satellite radio receiver to determine a geographical location of the terrestrial repeater as its own.
