Abstract: A method and apparatus for mitigating interference in a satellite signal receiver is described. The satellite signal receiver receives satellite signals from a plurality of satellites. In one example, a control signal is transmitted to the satellite signal receiver upon occurrence of data transmission from a wireless transceiver operating in proximity to the satellite signal receiver. Signal integration within the satellite signal receiver is gated in response to the control signal. In another example, one or more values of satellite signal samples are selected from a plurality of possible values. Signal integration within the satellite signal receiver is gated in response to a percentage of satellite signal samples taken over a predefined period exceeding a predefined threshold. In yet another example, a gain setting of an automatic gain control circuit within the satellite signal receiver is adjusted in response to detection of interference.

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).

Abstract: A communication device within a GNSS group propagates GNSS assistance data to one or more other communication devices in the GNSS group utilizing direct device-to-device connections. The GNSS assistance data comprises ephemeris received from one or more GNSS satellites and/or predicted ephemeris. As a source device, the communication device generates, and/or acquires from other resources such as a remote location server, the predicted ephemeris. As a destination device, the communication device receives existing GNSS assistance data from a source device and/or other communication devices in the GNSS group. A GNSS position for the communication device and corresponding time information are used to refresh the received GNSS assistance data. In instances where the communication device further acts as a relay device, the refreshed GNSS assistance data is relayed to other communication devices over wired and/or wireless direct device-to-device connections utilizing appropriate communication technologies such as WiFi, Bluetooth and/or Bluetooth low energy.

Abstract: A GNSS enabled mobile device receives GNSS assistance data in a determined format from a central processing station communicatively coupled to a wide area reference network (WARN). The WARN comprises a first plurality of GNSS tracking stations from which usable signals are received by the central processing station, and a second plurality of GNSS tracking stations from which unusable or no signals are received by the central processing station. The central processing station generates the GNSS assistance data using a complete set of GNSS reference feeds of the WARN. The complete set of GNSS reference feeds comprises actual GNSS reference feeds from the first plurality of GNSS tracking stations and virtual GNSS reference feeds derived for the second plurality of GNSS tracking stations from processed actual GNSS reference feeds. The generated GNSS assistance data is reformatted into a determined format and is communicated to the GNSS enabled mobile device, accordingly.
