Abstract
Method and apparatus for locating position of a mobile device in an assisted satellite positioning system is described. In one example, satellite measurement data is obtained from a plurality of satellites at a mobile device. Position of the mobile device is computed using the satellite measurement data. The position is sent to a cellular device via a wireless ad hoc network. In one example, the wireless ad hoc network comprises a BLUETOOTH communication link. In one example, the mobile device is configured to receive assistance data from a position server through the wireless ad hoc network. For example, the mobile device may comprise a housing configured to plug into a cigarette lighter connector of an automobile and the cellular device may comprise a cellular telephone without location-determination capabilities (i.e., the cellular telephone does not include an integrated GPS receiver).
