Satellite positioning system aiding using a secondary satellite receiver
First Claim
1. A method of determining an approximate location of a device within the footprint of a satellite position system satellite and a secondary satellite, comprising the steps of:
- receiving positional assistance information from the satellite position system satellite;
receiving positional assistance information including ephemeris data from the secondary satellite, wherein the secondary satellite is unassociated with the satellite position system satellite; and
determining the approximate location based on the positional assistance information from the satellite position system satellite and the secondary satellite.

Abstract
A method (400) and system (300) for determining an approximate location of a device (201) within the footprint of a SPS satellite (116) and a secondary satellite (114) can include a SPS receiver (104) for receiving positional assistance information from the SPS satellite, a secondary satellite receiver (102) for receiving positional assistance information such as ephemeris data from a secondary satellite, and a processor (310) for determining the approximate location based on the positional assistance information from the satellite position system satellite and the secondary satellite.
