Patent number: 7522588Abstract: 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.Type: GrantFiled: December 13, 2002Date of Patent: April 21, 2009Assignee: QUALCOMM IncorporatedInventors: Zoltan Biacs, Mark Moeglein, Justin McGloin

Patent number: 7460870Abstract: 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.Type: GrantFiled: April 24, 2003Date of Patent: December 2, 2008Assignee: QUALCOMM IncorporatedInventors: Mark Moeglein, Wyatt Riley

Patent number: 7383049Abstract: In a wireless telecommunication network, hybrid (GPS and AFLT) mobile stations provide redundant position information, which is used for time base calibration and/or correction of position measurements. Every mobile station (i.e., handset or cellular phone) can be used as a test instrument, and data from regular wireless phone calls can be supplemented by data from drive-around field test units. The time base and/or position offsets are stored in a base station almanac data base along with other information used for obtaining the most reliable position fixes under a variety of conditions. An automatic system is provided for creating, updating, and maintaining the base station almanac data base. The automatic system not only characterizes the performance of the wireless network but also characterizes the performance of the position determination system. The automatic system provides performance feedback to system operators and customers.Type: GrantFiled: March 7, 2002Date of Patent: June 3, 2008Assignee: Qualcomm IncorporatedInventors: James D.

Publication number: 20060276202Abstract: 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-GSM, 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.Type: ApplicationFiled: August 8, 2006Publication date: December 7, 2006Inventors: Mark Moeglein, Wyatt Riley

Patent number: 7065351Abstract: A method of obtaining data useful for one or more network applications is described. The method is performed responsive to a triggering event, such as a dropped call, a position fix, or even expiration of a timer. A position estimate for a subscriber station is obtained responsive to the event. A record is then formed associating the position estimate for the subscriber station with an identifier of the triggering event and/or data measured or obtained responsive to the event, such as the strength of one or more pilots visible to the subscriber station. The record is either stored locally or transmitted to a remote location. In one implementation, the record is transmitted to a remote location, and stored in a database holding like records relating to other subscriber stations.Type: GrantFiled: August 4, 2003Date of Patent: June 20, 2006Assignee: Qualcomm IncorporatedInventors: Stephen Carter, Mark Moeglein, James D.

Publication number: 20060103575Abstract: A system and method examines the quality of a positioning signal acquisition assistance window of an assisted position location system. The fit of acquisition assistance windows is examined using a posteriori knowledge of specific, or hypothetical, position measurements from a mobile station. A base station almanac manager compares mobile station measurement data to acquisition assistance window data, records an outcome based upon the comparison including a window quality value (WQ), or range of window quality values. Source data used in the generation of acquisition assistance windows is adjusted according to the window quality value.Type: ApplicationFiled: November 30, 2004Publication date: May 18, 2006Inventors: Mark Moeglein, Wyatt Riley

Publication number: 20050037775Abstract: 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.Type: ApplicationFiled: June 25, 2004Publication date: February 17, 2005Inventors: Mark Moeglein, Douglas Rowitch, Wyatt Riley, James DeLoach, Leonid Sheynblat

Patent number: 6185427Abstract: 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.Type: GrantFiled: April 28, 1998Date of Patent: February 6, 2001Assignee: SnapTrack, Inc.Inventors: Norman F.
