Method and system for a single rf front-end for gps, galileo, and glonass

Abstract

A wireless receiver receives satellite signals from a plurality of different satellite systems comprising GPS, GLONASS, and GALILEO. A single analog RF front-end is used to process the received satellite signals. The single analog RF front-end uses a single fix-valued analog frequency generated internally for simultaneously receiving the satellite signals comprising signals from a GPS frequency band, a GLONASS frequency band, and/or a GALILEO frequency band. The received satellite signals are separated into single frequency band signals within the GPS frequency band, the GLONASS frequency band, and/or the GALILEO band. Particular satellite channels associated with the single frequency band signals are determined based on corresponding satellite channel frequencies and satellite channel codes. The single analog RF front-end filters the received satellite signals to generate an upper sideband signal comprising signals within the GLONASS bands and a lower sideband signal comprising signals within the GPS bands and/or the GALILEO bands.
