  • System and method of location determination using multiple location inputs
    Patent number: 10578743
    Abstract: Systems and methods of determining a device position are described. GPS and cellular signals, in addition to VIO displacement are used to determine the device position via a loose or tight coupling algorithm. Both algorithms iteratively linearize base station position equations around an intermediate position that changes each iteration based on VIO displacement and solves the linearized solutions until convergence. The loose coupling algorithm uses the GPS fix as an initiation position, linearizing and solving using the base station equations only. The tight coupling algorithm linearizes both the base station and GPS position equations, using an arbitrary initial position. To account for multipath effects, the linearization and solution are performed for multiple random sets of measurements and the position with the smallest error metric is selected.

    Abstract: An array of antenna elements is energized as a plurality of concentric rings of the antenna elements, each of the concentric rings energized with a respective signal from a first transceiver, the signal having a continuously varying progressive phase between the antenna elements to generate n respective electromagnetic orbital angular momentum (OAM) beams each having a respective OAM mode m where m ranges from 0 to ±n. The beams are contemporaneously generated orthogonal to each other. The circumferential phase profile of the signal for a concentric ring of ? antenna elements is 2?m radians, and the progressive phase difference between each of the ? antenna elements is 2?m/? radians. The first transceiver transmits the beams to a second transceiver which demodulates them and sends demodulation quality information to the first transceiver for determination of whether to transmit the beams in full multiplexing, full diversity or partial diversity.
