The purpose is to evaluate the feasibility of several reduced order system models for implementation in an extended Kalman filter formulation whose estimates would be used to aid the tracker. The first filter model is a twelve state model in which filter estimates of the satellite inertial position and velocity are obtained and used in the estimation of the tracker states. A second, six state-model deletes these six satellite states, and tracker state estimation is accomplished by exploiting the information already available in the tracking geometry, dominant modes of satellite dynamics, and the range measurement. Tracker state estimation is accomplished in the line of sight coordinate frame for both filter formulations. A covariance analysis was performed, evaluating each filter against a 42 state truth model. The tracking profile used in the study was specifically designed to evaluate each filter's state estimation capability when faced with a highly nonlinear tracker angular rate history. It was concluded that the six state filter is a viable alternative, and, with some proposed modifications, is preferable (because of its simplicity and lower computational burden) and warrants further study.

This book was released on 1974 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 61-state truth model is developed for the aircraft to satellite tracking problem. The equations for the Extended Kalman Filter are described and the truth model is examined and simplified to give a 12-state reduced order filter model of the system. Using the method of Covariance Analysis which is described, the performance of the 12-state filter model against the 61-state truth model is evaluated with the dynamics profile of a high altitude aircraft tracking a near earth satellite in a circular polar orbit.
