Bruce E. Shuman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and system for determining a position of a transceiver in a communications network
    Patent number: 6313790
    Abstract: A method and system for determining a position of an orbiting transceiver in a communications network includes at least a first and second transceiver at a first and second known location, respectively, on Earth. The first and second transceivers are adapted to transmit and receive communications signals to and from the orbiting transceiver. A processor coupled to one of the first and second transceivers determines a first and second range measurement between each of the first and second transceivers and the orbiting transceiver, respectively, as well as corresponding first and second range rates representative of a time rate of change of the first and second range measurements.
    Type: Grant
    Filed: February 9, 2001
    Date of Patent: November 6, 2001
    Assignee: Hughes Electronics Corporation
    Inventors: Donald C. D. Chang, Kar W. Yung, William J. Nunan, David C. Cheng, Bruce E. Shuman
