| 摘 要： | 为了利用单星敏感器的测量数据确定导弹平台的三轴误差角,建立了平台在垂直星敏感器主轴的两个方向上的误差角近似模型,分析了方法误差的大小;并根据先验信息确定平台绕星敏感器主轴的误差角,同时对另两个轴的误差角进行修正.该方法能够较好地确定平台的三轴误差角,当先验信息不精确时,计算的平台绕星敏感器主轴方向的误差角不准确.

| Abstract: | In order to obtain platform error angles of axis X,Y,Z by single star sensor measured data,platform error angle model of two directions which are upright with the principal axis of star sensor was established,and the method error was analyzed. According to prior information,platform error angle around the principal axis was obtained,and another two error angles were amended. So such method provides a better way for obtaining platform error angles of axis X,Y,Z. But if prior information is not exact,the plat... |
