| 摘 要： | 应用捷联惯导系统的基本理论研究了动力调谐陀螺寻北仪在有姿态时，由于坐标不一致性和纬度的计算误差引入的寻北误差，为全方位补偿和姿态补偿提供了理论探索。仿真和实际系统结果表明，由方位角引起的方位角误差与纬度及姿态有关。

| Abstract: | The north finder error was studied using the basic theory of strap-down inertial system. It is found that when the attitude angle is nonzero, the azimuth error is partly caused by the disagreement of coordinates with latitude error. And based on this, the theoretic criteria of the azimuth and attitude compensation were partially put forward. Simulative and testing results show that the azimuth error is the function of azimuth, latitude and attitude. |
