New method of multi-sensor intelligent information fusion satellite attitude determination

To solve the problem that in the traditional satellite attitude determination system, the changes of conditions are unconsidered, viz. the traditional method lacks of module to eliminate the polluted data and applies a fixed method to process the data, an intelligent fusion scheme selection method is proposed based on NFE model. This method can eliminate the polluted data with wave gate, and compute the confidence of the attitude determination system by NFE model, and then select the matching fusion scheme according to actual situation to suit the practical attitude determination condition, which are verified by the computer stimulation results. So that it can be realized to get higher precision satellite attitude determination by using the fault avoidance module and the intelligent selection module.
