Greg M. Gutt 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).

  • LEO-based positioning system for indoor and stand-alone navigation
    Patent number: 8160576
    Abstract: A method for estimating a precise position of a user device from signals from a low earth orbit (LEO) satellite includes receiving at least one carrier signal at a user device, each carrier signal being transmitted a distinct LEO satellite. The user device processes the carrier signals to obtain a first carrier phase information. The user device recalls an inertial position fix derived at an inertial reference unit. The user device derives a position of the user device based on the inertial position fix and the first carrier phase information.
    Type: Grant
    Filed: February 6, 2009
    Date of Patent: April 17, 2012
    Assignee: The Boeing Company
