Abstract

A Consider Kalman Filter is implemented to add the uncertainty in parameters related both to the quiescent system dynamics and to the maneuver dynamics to a Variable State Dimension filter (VSD). By adding the extra uncertainty from mildly observable parameters related to the maneuver, this approach provides a low-computational-cost improvement over the nominal VSD for orbit determination of an uncooperative spacecraft. Simulations are conducted for a continuously thrusting spacecraft with no a priori knowledge of the maneuver duration. Results have shown improved orbit estimation and thrust levels for both a single model VSD filter and an interacting multiple model VSD.
