  • Real time precision orbit determination system
    Patent number: 6133872
    Abstract: The present invention relates to a system for providing highly accurate position estimates for a vehicle in space, in substantially real time. The system includes a Mission Control Center (MCC) that calculates precise orbits for GPS satellites that are in view of the vehicle, using GPS tracking data from the worldwide network of tracking sites. Because the tracking data from the tracking sites is not current when received by the MCC, the precise GPS orbits are "propagated forward in time" by the MCC. The propagated orbit information is uploaded to the user satellite where it is processed in an extended Kalman filter, or similar device, along with the real time output of the on-board GPS receiver, to achieve highly accurate satellite location estimates in substantially real time.
