  • Patent number: 11777207
    Abstract: A virtual phased-array and associated methods are disclosed for coherent transmission and/or reception of radio signals among antenna elements of the array, where the antenna elements are wirelessly interconnected and one or more of the elements may be moving. In one embodiment, clocks of the antenna elements are synchronized based on a first set of measurements of wireless signal(s) transmitted by one or more of the antenna elements. Relative positions and orientations of the antenna elements are determined based on a second set of measurements of wireless signal(s) transmitted after the synchronizing of the clocks. Weight(s) of a manifold vector are determined based on the relative positions and orientations, to calibrate the manifold vector. A plurality of coherent wireless signals are transmitted via two or more of the antenna elements based on the calibrated manifold vector.

  • Patent number: 10094908
    Abstract: A geolocation system includes an originator device configured to transmit a first wireless signal to a transponder device. The transponder device is configured to transmit a second wireless signal to the originator device. The system includes at least one observer device configured to receive the first wireless signal from the originator device and receive the second wireless signal from the transponder device. The system also includes a first processor configured to calculate a transactional difference range at the at least one observer device based on the first wireless signal received at the observer device and the second wireless signal received at the observer device. A corrected transactional difference range value may be calculated by subtracting a time-of-flight of the first wireless signal from the originator device to the transponder device from the transactional difference range. A method of performing geolocation using a transactional difference range is also disclosed.

  • Patent number: 9140557
    Abstract: A system and method for estimating the position of an object, such as a person, animal, or machine. The system includes first and second inertial measurement units, a first and second originator antennas, and a first and second transponder antennas. The system uses data from the inertial measurement units to estimate a position of the object. The system also calculates a range measurement between the first originator antenna and first transponder antenna. The system calculates a first CPD measurement between the second transponder antenna and the first originator antenna, and a second CPD measurement between the second originator antenna and the first transponder antenna. The range measurement and at least one CPD measurement are used to update a Kalman filter for estimating the position of the object. The system determines also updates the Kalman filter when one of the inertial measurement units is in a zero-velocity condition.
