A U.K.-based company announced what it calls enhanced Global Positioning System at Mobile World Congress. According to CSR, its eGPS system will work indoors with weak or no GPS coverage, and still provide a faster time to first fix than aGPS does. eGPS uses existing information from the cellular network when there is little or no GPS signal to provide information to the location system. It combines the information gathered via the cellular network with GPS data and uses less power and gets a stronger lock than aGPS.
