Abstract

Abstract: This paper presents a fault-tolerant method for estimating the angular rate of uncontrolled bodies in space, such as failed spacecraft. The bodies are assumed to be free of any sensors; however, a planned mission is assumed to track several features of the object by means of stereo-vision sensors. Tracking bodies in the space environment using these sensors is not, in general, an easy task: obtainable information regarding the attitude of the body is often corrupted or partial. The developed method exploits this partial information to completely recover the attitude of the body using a basis pursuit approach. An unscented Kalman filter can then be used to estimate the angular rate of the body. Abstract : Highlights: The proposed solution estimates angular rate of a failed spacecraft. Angular rate estimation is performed starting from attitude information recovery. The method is thought to be applied in case of corrupted and partial input data. Typical occlusions of stereovision sensors for features tracking are overcome. The results of our approach are comparable with the ones obtained with other methods in the literature.
