Abstract: A method and apparatus for distributing satellite navigation data is described. In one example, satellite signals are processed at each of a plurality of reference stations to receive a respective plurality of satellite navigation data streams. Packets are formed in response to said plurality of satellite navigation data streams to generate a plurality of packetized satellite navigation data streams. The packetized satellite navigation data streams are sent to a processing system. The processing system removes duplicate packets within said plurality of packetized satellite navigation data streams to generate a combined packet stream. The combined packet stream is then sent into a communication network.

Abstract: A method and apparatus for determining time-of-day in a mobile receiver is described. In one example, expected pseudoranges to a plurality of satellites are obtained. The expected pseudoranges are based on an initial position of the mobile receiver and an initial time-of-day. Expected line-of-sight data to said plurality of satellites is also obtained. Pseudoranges from said mobile receiver to said plurality of satellites are measured. Update data for the initial time-of-day is computed using a mathematical model relating the pseudoranges, the expected pseudoranges, and the expected line-of-sight data. The expected pseudoranges and the expected line-of-sight data may be obtained from acquisition assistance data transmitted to the mobile receiver by a server. Alternatively, the expected pseudoranges may be obtained from acquisition assistance data, and the expected line-of-sight data may be computed by the mobile receiver using stored satellite trajectory data, such as almanac data.

Abstract: A global navigation satellite system (GNSS) enabled mobile device may be operable to monitor and determine counts at which autoblank signals are asserted over time intervals corresponding to consecutive time windows during the RF interference mitigation process using autoblanking. The GNSS enabled mobile device may be operable to disable the generation of a blank signal when the count may be greater than a particular count threshold at the end of the time window. The GNSS enabled mobile device may be operable to enable the generation of a blank signal when the count may be less than or equal to a particular count threshold at the end of the time window. The blank signals may be used to blank the processing of the received GNSS signals.

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, data transmission of a wireless transceiver operating in proximity to the satellite signal receiver is monitored. A control signal is transmitted to the satellite signal receiver upon occurrence of data transmission from the wireless transceiver. Signal integration within the satellite signal receiver is then gated is response to the control signal. In another example, one or more values of satellite signal samples are selected from a plurality of possible values. A percentage of satellite signal samples having the one or more selected values is monitored over a predefined period. Signal integration within the satellite signal receiver is gated in response to the percentage 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.
