| Abstract: |
| The measurement data of star sensor for three-axis stabilized satellites’ attitude often need to be converted to the Euler angle in a reference coordinate system. In view of this,the conversion methods are summarized,including the conversion from star sensor data to attitude matrix and conversion from attitude matrix to the Euler angles. From the programming point of view,a way to calculate full-scale Euler angle is also given under 312&321 transform orders which are often used in project. Then some error factors are analyzed,and the transform order suggested for geostationary satellite is also provided according to analysis.The results indicate that the method is correct and useful for the attitude calculation and error analysis of three-axis stabilized satellites. |
