    Abstract: PROBLEM TO BE SOLVED: To provide systems, methods, and apparatus for a frequency control.SOLUTION: A receiver according to one embodiment includes a frequency control unit configured to receive a stream of samples including a plurality of received instances of a transmitted signal. The frequency control unit is configured to output a first correction signal (e.g. indicating a rotation) that is based on more than one of the received instances and a second correction signal (e.g. to control an oscillator) that is also based on more than one of the received instances. In some embodiments, a controlled oscillator is used to receive and/or transmit another signal, such as a signal received from a GPS space vehicle. In other embodiments, the received instances are from a GPS signal. In further embodiments, a fixed-frequency oscillator is used, and the second correction signal is used to receive and/or transmit another signal, such as a GPS signal.

    Abstract: PROBLEM TO BE SOLVED: To provide a system and method for acquiring signal acquisition assistance data. SOLUTION: The signal acquisition assistance data is acquired for receiving devices, such as wireless position assisted location devices seeking signals from any source, such as satellite vehicles and base stations. The data may be acquired from previously acquired data, based on evaluation of changes in parameters, such as time and location that may jeopardize validity. Refined data may be calculated by a receiver using partial measurements of signal sets, particularly if the acquisition assistance data provided by a remote entity includes more distinct parameters than have typically been provided. New data need not be acquired until the validity of previous data expires due to limitations upon temporal extrapolation using Doppler coefficients, unless mobile station movement that cannot be compensated is detected, and jeopardizes validity of the previous data.

    Abstract: PROBLEM TO BE SOLVED: To achieve position determination in a wireless communication system with detection and compensation for repeaters. SOLUTION: In order to detect whether or not a remote terminal is under the coverage of a repeater in a wireless communication network, techniques may be based on (1) a list of base stations expected to be received under the coverage of the repeater and (2) a characterized environment of the repeater or (3) a propagation delay for a transmission received at the remote terminal. Additional ambiguity resulting from being under the coverage of the repeater may be also accounted for or compensated by (1) discarding time measurements from repeated base stations, (2) adjusting processing for position estimates, and (3) computing a series of position estimates based on multiple transmissions received from the same originating base station and selecting the best estimate, or (4) computing a series of position estimates based on multiple transmissions from multiple originating base stations and selecting the best estimate.

    Abstract: A GPS communication system including a server and a client, each including a GPS receiver, for reducing the code phase search space of the GPS receiver of the client. The communication system includes a transmitter for transmitting timing information from the server to the client to help the client locate a first satellite, and a receiver for using timing differences between the satellites to synchronize and locate other satellites. The code phase search space is reduced by reducing the number of phase hypotheses that must be calculated to establish communication between the server and the client.

    Abstract: Signal acquisition assistance data is obtained for receiving devices such as wireless position assisted location devices (208, 210) seeking signals from any source (B1-B10), such as satellite vehicles and base stations. The data may be obtained from previously acquired data, based upon evaluation of changes in parameters such as time and location that may jeopardize validity. In some cases the data may be adjusted for the changes in parameters. Refined data may be calculated by a receiver using partial measurements of signal sets, particularly if the acquisition assistance data provided by a remote entity includes more distinct parameters than have typically been provided. New data need not be obtained until the validity of previous data expires due to limitations upon temporal extrapolation using Doppler coefficients, unless mobile station movement that cannot be compensated is detected, and jeopardizes validity of the previous data.

    Abstract: A communication system that allows multiple data applications to work simultaneously within a distributed execution environment in which only one IP address is assigned to the mobile system by an external wireless network. The mobile system comprises a wireless communication system with a first processing device (such as a cell phone or a network card) and a second device with another processor (such as a laptop computer or a personal digital assistant). The single IP address is assigned to the second processor, and all incoming external communications are stored in the second processor. In some embodiments the first processing device includes a filter; in other embodiments the second processing device includes a proxy for each processor. Additional processors can be connected to the mobile system by adding an additional filter or additional proxy.
