The Extended Kalman Filter Applied to the Determination of the Orbital Parameters of a Passive Earth Satellite.
Abstract
The extended Kalman filter is used to determine estimates of the orbital parameters, including drag, of a passive earth satellite. Actual tracking data from earth based radars were used and the orbital parameter estimates compared favorably with estimates obtained by other investigators using differential correction techniques. Also investitated was the utility of the extended Kalman filter for obtaining a sustained estimate of orbital parameters through several orbits with large data gaps and different radar site data for each orbit. The extended Kalman filter was not as effective under these circumstances, however, ad-hoc procedures were developed to sustain the estimate. (Author)
