Multichannel Robust Parameters Estimation for Disabled Satellites
School of Astronautics, Northwestern Polytechnical University, Xi’an
Based on the dual vector quaternions, this paper modeled both the kinematics and dynamics of the disabled satellites. In addition, considering the complex space environment may lead to the measurements failure of the target, a novel robust federal Kalman filter based algorithm (DVQ-REKF) is proposed by this paper. By utilizing the designed algorithm, both the pose and inertial parameters can be estimated in the same time when the measurements by each of the monocular camera on the service satellite failed for a certain period of time. Finally, the simulation shows the validity of the designed DVQ-REKF.
