Abstract: A geographic cell identification (cell ID) database is updated on the fly as, for example, roaming user equipment (UE) reports its location during Assisted Global Positioning System (A-GPS) operations. The cell ID database relates network locations to corresponding geographic locations. The cell ID database is used to retrieve a corresponding geographic location in response to the network location at which the UE reports being located. If it is found that the cell ID database does not contain the network location reported by the UE, the geographic location of the UE can be estimated using information in the reported network location, such as Mobile Network Code, Mobile Country Code, Local Area Code and Cell ID. The geographic location can then be used to obtain A-GPS assistance data for the UE. Once assistance information has been provided to the UE and the UE has determined its geographic location, the cell ID database can be updated with the determined geographic location.

Abstract: Method and apparatus for locating position of a remote receiver is described. In one example, long term satellite tracking data is obtained at a remote receiver. Satellite positioning system (SPS) satellites are detected. Pseudoranges are determined from the remote receiver to the detected SPS satellites.

In addition, position of the remote receiver is computed without obtaining an initial position estimate from a server or network.

Abstract: A mobile station database of cellular identifications and associated position information is stored in mobile station memory. The mobile station uses the position information in the database to assist in determining a current position for the mobile based on an identifier, such as cell ID, base station BSIC, PSC, or carrier frequency. A satellite vehicle signal is searched in an uncertainty region that is a function of position information associated with the current identifier. The uncertainty region can be limited by assumed platform dynamics via predefined velocity and acceleration information. Time maintenance for the mobile station can also be achieved through known approximate position from the position database and measurement of a single satellite vehicle propagation delay. The mobile station can compare a position determination obtained through satellite vehicle signals with position database information to determine the validity of that position.

Abstract: A method of determining a bit boundary of a GLONASS string is provided. In this method, a global position receiver can remove the meander sequence from bits of a GLONASS signal. After removing the meander sequence, time averages of bit energies for 20 possible (consecutive) bit boundary positions can be computed. At this point, the receiver can select a position from the 20 possible bit boundary positions that maximizes bit energy. A maximum accumulated value at this position as well as offset accumulated values at 5 ms and 15 ms offset from the position can be determined. Then, the receiver can determine whether a ratio of at least one of the offset accumulated values to the maximum accumulated value meets a predetermined condition. When the ratio meets the predetermined condition, the receiver can output the position as the bit boundary of the GLONASS string.

Abstract: A mobile tracking device is provided that monitors or measures one or more signals from GPS satellites and remote wireless base stations during a GPS acquisition process and a registration process, and terminates the process(es) prior to reaching a default timeout when the signals do not meet a predetermined threshold or value.
