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.
