  • Patent number: 9945959
    Abstract: A stand-alone radio frequency (RF) hardware component comprises first and second antennas, a digitizer, a serializer, and a serial output. The first antenna receives, over-the-air, a first analog Global Navigation Satellite System (GNSS) signal in a first frequency band. The second antenna receives, over-the-air, at least a second analog GNSS signal in a second frequency band, wherein the first frequency band and the second frequency band are separate and distinct. The digitizer digitizes the first analog GNSS signal into a first digitalized GNSS signal and digitizes the second analog GNSS signal into a second digitized GNSS signal. The serializer serializes the digitized GNSS signals into a serialized output signal. A wireless transmitter for wirelessly transmitting the digitized GNSS signals, as the serialized output signal, from the radio frequency hardware component to a separate communication device.

  • Patent number: 9921291
    Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to perform a distance travelled estimate with a mobile device. The distance travelled estimate is performed by determining a quality of displacement between a base position and each new position for the mobile device, which is determined based on the displacement between the positions and their associated uncertainties. If the quality of displacement is sufficient, the distance travelled estimate is updated using the displacement between the positions. Multiple tiers may be used, where, for example, if the quality of displacement is sufficiently high, the displacement associated with a preceding position may be excised from the distance travelled estimate and replaced with the displacement associated with the new position. Additionally, if the quality of displacement is even greater, the new position may be set as the base position.

    Abstract: Distributed antenna systems provide location information for client devices communicating with remote antenna units. The location information can be used to determine the location of the client devices relative to the remote antenna unit(s) with which the client devices are communicating. A location processing unit (LPU) includes a control system configured to receive uplink radio frequency (RF) signals communicated by client devices and determines the signal strengths of the uplink RF signals. The control system also determines which antenna unit is receiving uplink RF signals from the device having the greatest signal strength.

The method may also include formatting, via the sensor controller, the secondary position data. The method may also include aggregating, via the sensor controller, the formatted position data. The method may also include providing, via a single channel interface between the sensor controller and the main processor, the aggregated position data to an operating system installed on the main processor. The method may also include communicating, via a driver installed on the operating system, the position data to an application installed on the operating system.

  • Patent number: 8988284
    Abstract: A system and method for monitoring and tracking the position of a subject comprises, in an exemplary embodiment, a transponder configured for being co-located with the subject and a means for enabling communication between the transponder and a remote GPS-enabled receiver, such as a cell phone or the like, for selectively triangulating the position of the transponder. In the exemplary embodiment, the means for enabling such communication is software that is installed in and executed by the receiver. The software allows the receiver to triangulate the geographic position of the transponder by fixing a first reference point based on the location of the GPS-enabled receiver, fixing a second reference point based on the location of a network broadcast site through which the receiver and transponder communicate, and calculating the location of the transponder based on the angular position of the transponder relative to the network broadcast site.

  • Patent number: 8981902
    Abstract: A method and apparatus for controlling location information at a computer device such as a mobile telephone. Location information is intercepted and obtained by, for example, intercepting it from an Application Programming Interface destined for a location application. The location application is identified, and a rule is determined for applying to the location information on the basis of the identified location application. The rule is applied to the location information to give amended location information, and the amended location information is then sent to the location application.

  • Patent number: 8949011
    Abstract: A system for maneuvering an aircraft for operations in connection with a sea-going vessel, the vessel having a designated area for landings and sling-load operations. Each of the aircraft has a navigation unit (INU) comprising a GPS receiver and an inertial navigation unit. The INU's are updated by data from the GPS receivers and the data from the shipboard unit's GPS receiver and INU are transmitted to the aircraft. The aircraft performs RTK calculations to determine a vector to the shipboard GPS antennas and modifies the vector with data from the INU's.

  • Patent number: 8930136
    Abstract: A personal navigation device configured to determine heading readings continuously using data from a sensor in the personal navigation device. Heading readings are selected corresponding to a periodic event. A representative heading is determined from the selected heading readings. When a portion of the selected heading readings has a value within a range of the representative heading, a static heading indicator is asserted to indicate the personal navigation device is moving in a static heading. The static heading indicator may be used to smooth an estimated trajectory of the personal navigation device.

  • Patent number: 8909471
    Abstract: A position determining voting system that uses Doppler information from an on-board weather radar to improve the system's accuracy and/or fault tolerance includes a comparison function and an error integration function. The comparison function is used to monitor the independent position sources for correct operation, comparing and identifying a position source that should not be used based on its relative error compared with the other position sources and their characteristics. The integration function provides corrections to relative position sources by integrating the data from multiple absolute position sources when they are mutually consistent.

  • Patent number: 8862398
    Abstract: A system for tracking objects that are in earth orbit via a constellation or network of satellites having imaging devices is provided. An object tracking system includes a ground controller and, for each satellite in the constellation, an onboard controller. The ground controller receives ephemeris information for a target object and directs that ephemeris information be transmitted to the satellites. Each onboard controller receives ephemeris information for a target object, collects images of the target object based on the expected location of the target object at an expected time, identifies actual locations of the target object from the collected images, and identifies a next expected location at a next expected time based on the identified actual locations of the target object. The onboard controller processes the collected image to identify the actual location of the target object and transmits the actual location information to the ground controller.
