    Abstract: Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

    Abstract: A method for assisting in locating a position of a mobile wireless device comprises: obtaining visible-station indications identifying base stations that are visible from the mobile wireless device, the base stations comprising at least one cooperative terrestrial base station and at least one uncooperative WiFi terrestrial base station capable of bi-directional communications and configured to prevent data and/or voice communications with the mobile wireless device; sending, to an almanac processor, an indication of an approximate location of the mobile wireless device that comprises the visible-station indications; receiving an almanac of base stations comprising at least some of the visible-station indications and location indications indicating locations of the base stations visible from the mobile wireless device that correspond to the at least some of the visible-station indications; and determining a location of the mobile wireless device using the location indications.

    Abstract: Disclosed aspects relate to methods and apparatus for correcting a first sensor clock of a first sensor. The disclosed methods and apparatus effectuate receiving first and seconds signals in a sensor from a processor at known different times related to the timing of the processor clock. Based on the measured time interval between the times of the first and second signals as determined by the sensor, a clock correction factor may be determined in the sensor for correcting the timing of the sensor clock to be synchronized with the processor clock.
