  • Method and apparatus for determining the geographic location of a device
    Patent number: 7948435
    Abstract: A method and apparatus for determining the location of a device from signals provided by a plurality of satellites. A device receives a first plurality of signals comprising one signal from each of a first plurality of satellites and determines a first location of the device as a function of the first plurality of signals. The device then determines a second location thereof as a function of a second plurality of signals if the first location is not within a predetermined threshold. The second plurality of signals is a first subset of the first plurality of signals.

  • System and method for determining falsified satellite measurements
    Patent number: 7940213
    Abstract: A system and method for determining whether a wireless device has transmitted one or more forged satellite measurements. An estimated location of a wireless device may be determined as a function of signals from a cellular network. For each one of a first set of satellites from which the wireless device receives a signal, expected frequency information may be determined as a function of the estimated location, actual frequency information may be measured, and the expected frequency information compared with the measured frequency information. One or more satellite measurements received from the wireless device may then be identified as forged if a difference between the expected and measured frequency information is greater than a predetermined threshold.

  • Method and apparatus to select an optimum site and/or sector to provide geo-location data
    Patent number: 7933610
    Abstract: A system and method selects secondary base stations to task that provide geo-location information used to geo-locate a mobile station. A network overlay location system may be co-located at base station sites of a wireless communications network. The location measurement units of the network overlay system provide location information of the mobile station, which may be determined via one or more geo-location techniques, for example: time of arrival (TOA), time difference of arrival (TDOA), uplink time difference of arrival (UTDOA), angle of arrival (AOA), signal power, radio fingerprinting etc. Selecting secondary base stations to task using various selection criteria may provide optimum results when geo-locating a mobile station.

  • LOCATION MEASUREMENT ACQUISITION ADAPTIVE OPTIMIZATION
    Publication number: 20110090122
    Abstract: A disclosed method uses the results of location queries to tune the value of measurements of a property to obtain a statistically representative measurement for geo location. As location requests arrive, a current measurement value associated with the serving area or location is used to determine the number of measurements to obtained; the resulting uncertainty is mapped against the number of measurements required to determine that value. If additional measurements are required to achieve the target uncertainty in the result, this is recorded. The process relies on empirical observations and has the additional advantage of being blind to the actual network topology. This approach by its own nature automatically takes into account network changes whether known or unknown.

  • LOCATION MEASUREMENT ACQUISITION OPTIMIZATION WITH MONTE CARLO SIMULATION
    Publication number: 20110090121
    Abstract: The present subject matter discloses a method for estimating dilution of precision (DOP) across a service area. A Monte Carlo simulation is used to determine the DOP across a service area. Random points are selected across a service area and as well as the radio transmitters who signals are capable of being received at the random points are determined. Using the network topology of radio transmitters, a DOP is calculated for each of the random points. DOP is modeled for the service area as a function of the calculated DOP for each of the random points. The modeled DOP is used to determined the measurement accuracy required for subsequent location requests.

  • System and method of operation for network overlay geolocation system with repeaters
    Patent number: 7925205
    Abstract: A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters is disclosed. Embodiments of the novel system and method enable wireless communication system to determine if signals being received by system receivers arrive directly from a target mobile appliance or if the signals are passing through a repeater. The system's determination may be based at least in part on the TA of the signal, the power of the received signal, the power of the transmitted signal, the hearabiltiy of the signal at system receivers, the hearabiltiy of system transmitters at the mobile and the known delays associated with the repeaters. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.
