  • Patent number: 9940765
    Abstract: In providing secure data access, a secure data device receives a data access request to access secured data stored in a storage of the secure data device. A location module of the secure data device calculates a current location of the secure data device. A secure data module of the secure data device compares the current location and a pre-stored location stored in the secure data device. Upon determining that the current location matches the pre-stored location, the secure data module retrieves the secure data from the storage and processes the secure data. The processed secure data is sent as available data in response to the data access request. Upon determining that the current location does not match the pre-stored location, the secure data module retrieves the secure data and processes the secure data in a manner that renders the available data unusable.

  • Patent number: 9557422
    Abstract: Systems, methods, devices and subassemblies for creating and delivering a GNSS augmentation service include one or more reference stations for receiving signals transmitted by navigation beacons and an augmentation server coupled to the reference stations. At least one of the reference stations is able to receive at least one of the signals from a low earth orbit satellite. Each of the reference stations determines first navigation observables based on the received signals and transmit information associated with the first navigation observables to the augmentation server. The augmentation server is configured to determine and distribute augmentation information to a receiver. The augmentation information is based on the received information associated with the first navigation observables, locations of the reference stations, and computational models.

  • Patent number: 9530141
    Abstract: Using a bi-directional transceiver, one can receive or provide a service. Location of the parties associated with respective transceivers is tracked and billing is made accordingly based on factors such as time spent returning to a vehicle, being inside or outside the location, and the like. Further, a location where a job is to be performed is checked for its zoning information to ensure that a person performing the job is not only licensed to perform the job, but licensed to work at a specific zoned location where not all who are licensed in the field are licensed to do so.

  • Patent number: 9513376
    Abstract: The disclosed invention embodies a system and method for multi-sensor, multi-frequency, multi-constellation data integration providing integrated onboard positioning of a vehicle. Multiple correlators perform autonomous signal quality monitoring to avoid the need for external augmentation systems. The integrated method and system typically includes multi-constellation, multi-channel GNSS and may consider positioning information from one or more other positioning resources including onboard, airborne, and ground-based signals. The positioning information from these functions are used in combination to exclude an erroneous signal from consideration while providing an integrated, blended precision positioning solution with improved size, weight, power and cost characteristics.

    Abstract: An example method for independently verifying a transit point in a network environment is provided and includes receiving, at a transit point in a packet network, at least two radio signals from corresponding different radio sources, receiving, at the transit point, a sampling request in an packet message, and transmitting in another packet message a sample of the at least two radio signals such that by comparing the sample with an expected sample, a location of the transit point is determined. The expected sample can comprise another sample of the at least two radio signals that would have been received by the transit point at an expected location at a time of receipt of the sampling request, and if the expected sample matches the sample, the transit point is determined to be at the expected location.

  • Patent number: 9420421
    Abstract: A least squares geofence method that minimizes trigger misfires caused by data variability and location blunders and minimizes delayed/missed entry triggers generated under urban or indoor conditions. The least squares geofence method uses a weighted least squares (LS) model to compute a location estimate for a target device. A LS location estimate is used to determine if a target device is located inside or outside a predefined geofence. The present invention additionally comprises a Kalman filter geofence method that further improves the accuracy of entry/exit geofence triggers. A Kalman filter geofence method uses a Kalman filter to filter location data retrieved for a target device. Filtered location data is used to determine if a target device is located inside or outside a predefined geofence. A Kalman filter geofence method estimates velocity and heading information for a target device to generate accurate entry/exit geofence triggers for devices in fast moving mode.
