    摘要: Methods and apparatuses for location determination in wireless assisted positioning systems. In one aspect of the disclosed method and apparatus, a method to determine a position of a mobile device in a positioning system includes: computing a second estimated position of a mobile device using a first assumed geometric relationship for a location of the mobile device in relation to a navigational transmitter (e.g., a basestation, a pseudolite, or a Satellite Positioning System (SPS) satellite). The first geometric relationship is linearly independent from the altitude of the mobile device (e.g., obtained from an altitude aiding) and a second geometric relationship based on range information (e.g., a range from the mobile device to the navigational transmitter, a pseudorange, an arrival time, or a round trip time) measured with respect to the navigational transmitter. In another embodiment of the disclosed method and apparatus, the method to determine a position of a mobile device in a positioning system includes: determining an estimated clock bias from a strength indicator of a signal transmitted from a navigational transmitter to the mobile device.

    摘要: A method and apparatus for creating and using a base station almanac for position determination is described. The base station almanac includes a number of records, where each record can describe a sector or a transmitter (e.g., a base station or a repeater) in a wireless communication network. Each record includes a protocol type field that indicates the one or more protocols supported by the record (e.g., IS-801, J-STD-36, GSM, W-CDMA, and so on). Each record also includes a unique sector identifier for the sector/transmitter for each supported protocol, where each identifier is defined based on the associated protocol. A record may also include multiple maximum antenna ranges (MARs), where each MAR is associated with a respective reference power level. One of the multiple MARs can be selected for use for position determination depending on received signal strength. The base station almanac further includes other features.

    摘要: 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.

    摘要: A system and method of preprocessing reference data in a reference assisted location technology are disclosed. A plurality of reference stations each provides reference data over a network to a preprocessing. The preprocessor analyzes the data from the multiple reference stations and eliminates multiples sets of redundant data. In addition, the preprocessor can perform quality assurance checks on the data as well as the status of the reference stations themselves. Non-redundant data may also be preprocessed to perform differential GPS calculations. The preprocessed data is transmitted to one or more position servers for additional processing and position determination.

    摘要: A system and method for processing in a distributed manner satellite position system (SPS) information. In one example of the invention, a first mobile SPS receiver receives SPS signals from a plurality of SPS satellites and transmits a position information to a wireless cell based station which is coupled to a first communication network. The wireless cell based station is coupled to a first digital processing system which receives the position information from the wireless cell based station and calculates a location of the first mobile SPS receiver based upon the position information. The first digital processing transmits this location, usually without any presentation of this location on the first digital processing system, to a remotely located application digital processing system which presents the location to a user of the application digital processing system.
