    Patent number: 6070078
    Abstract: A Global Positioning System (GPS) receiver located at a base station of a cellular telephone network determines the location of the base station and obtains GPS ephemeris and, if available, timing information. A server uses the obtained information to calculate auxiliary information for use by a GPS receiver. The base station transmits the auxiliary information to the GPS receiver which is located within a cellular telephone operating within the service area of the base station. The cellular telephone GPS receiver uses the auxiliary information to determine the location of the cellular telephone and transmits location information to the cellular telephone network via the cellular telephone and the base station.
