    摘要: A system, method and apparatus are provided which relate to calibrating a wireless access point so as to allow proper synchronization of mobile wireless devices connecting to the wireless access point. A closed-loop filter is used to more accurately synchronize times and to more accurately determine the location of the access point for purposes of determining the position of a mobile station.

    摘要: A method and apparatus for using a predetermined portion of terrain elevation maps in a database for aiding in computing a three-dimensional position of a wireless station. Instead of using the entire terrain model of the earth or an entire country, the database consists of an incomplete model, which includes only the most populous areas or specific regions. This reduces the size of the information in the database, which in turn reduces the amount of time to compute the positions of the wireless device.

    摘要: Location profile is used as a way of optimizing power consumption of communication devices such as mobile handsets and smart phones which tend to have facilities for multiple wireless methods for communication. This is done by correlating the availability of the wireless signals to the specific zones in the user location profile. The method learns the wireless environment of each zone and subsequently while the device is detected to be in the same zone, intelligently prioritizes use of different communication methods for that zone, and turns off all unnecessary communication options, thereby reducing power consumption.

    摘要: An embodiment of the present invention is a combined GPS and dead-reckoning (DR) navigation sensor for a vehicle in which a pair of modifications are made to an otherwise conventional Kalman filter. Process noise is adapted to cope with scale factor errors associated with odometer and turning rate sensors, and correlated measurement error processing is added. When only two Doppler measurements (PRRs), or three with an awkward three-satellite geometry, are available, DR error growth can nevertheless be controlled. The measurement error correlations in the conventional Kalman filter covariance propagation and update equations are explicitly accounted for. Errors induced by selective availability periods are minimized by these two modifications.
