Abstract (en)
[origin: WO03008991A2] A method for processing positioning signals is provided that includes receiving positioning signals at a ranging receiver from a plurality of satellites. Carrier frequency offset (CFO) results are determined at the ranging receiver based on the positioning signals. The CFO results are provided to a geolocation processor. Satellite information for the plurality of satellites is determined at the geolocation processor based on the CFO results. The satellite information is provided to the ranging receiver. Pseudorange data for the ranging receiver is determined at the ranging receiver based on the satellite information.
