| Abstract: | A method of attitude determination using combined sensors is presented for satellite equipped magnetometer and globe positioning system (GPS) in this paper. Algorithms are designed and simulated for attitude determination using measuring information of both equipment based on Kalman filtering algorithm. The destination of the algorithm combined by both information is to improve the accuracy and reliability of autonomous attitude determination. The result shows that the precision of attitude determination of the system is improved. |
