| Abstract: | This paper makes research on an attitude determination system for a sun synchronous satellite during normal mode operation. Based on Extended kalman Filtering technique, an attitude estimator is designed which adopts the quaternion representation and, thus, is more integrate and accurate. The observability of the attitude estimator is also analyzed. Simulation results show that precision attitude determination is achieved using the attitude determination algorithm derived in this paper. |
