Steep growth in location-based services and applications, riding on the wave of the mobile market, is expected in years to come. GPS/GALILEO engines embedded in cellular phones will allow network-based positioning, such as the GSM network and WCDMA network, to be implemented. However, challenging issues have to be overcome before the integration can be done successfully. This paper will discuss about the single RF front-end GPS equipped with GALILEO capability, designed to be integrated into an embedded system, such as the cellular phone. The receiver architecture is selected to have the flexibility for integrating into a larger system.
