  • Extended kalman filter for autonomous satellite navigation system
    Patent number: 6859170
    Abstract: An autonomous navigation system for an orbital platform incorporating a global positioning system based navigation device optimized for low-Earth orbit and medium-Earth orbit applications including a 12 channel, GPS tracking application-specific integrated circuit (15) operating in concert with a computer system (90) implementing an extended Kalman filter and orbit propagator which autonomously generates estimates of position, velocity and time to enable planning, prediction and execution of event-based commanding of mission operations.
    Type: Grant
    Filed: December 30, 2002
    Date of Patent: February 22, 2005
    Assignee: The Johns Hopkins University
    Inventors: William S. Devereux, Albert A. Chacos, Mark S. Asher, Dennis J. Duven, Thomas L. Kusterer, Richard C. Morgan
