A new approach to improving the accuracy of attitude determination - A redundant measurement model method

The usual methods for attitude determination of spinning satellite have been mentioned in many papers published abroad. The common disadvantage of these methods is the existence of many singular points at which the determination of attitude accuracy differences is of no practical value. Date and time for the launch of the satellite have to be selected meticulously so as to get better attitude determination results. In order to overcome this disadvantage, the concept of redundant measurement model is presented. Because of the application of the redundant measurements models for attitude determination, singular point distributions in the usual methods have been improved, the accuracy is higher and the launch window has been expanded.
