yaw error meaning in English
偏航误差
Examples
- The position errors are measured by two dimension single - frequency laser interferometer , the pitch and yaw errors are tested using phase shifting interferometer with a resolution of 0 . 1nm , the linearity along motion axis is investigated by autocollimator with 0 . 01 " uncertainty
利用单频激光干涉仪测试其运动定位误差特性，相位偏移干涉法测试运动转角误差，光电自准仪测试其运动偏摆误差。 - Because the ins error equation is unstable , some initial states error will cause error floating and error accumulating , if the filter observations were only position error , kalman filter will converge very slowly , and some states error ( such as yaw error ) will be great . since the milemeter altimeter and piloting could only output position information , this paper put forward a method , firstly estimateing states and then kalman filtering , to improve filtering effect . simulation proved that this method could effectively reduce the system states error , quicken filtering convergence and improve filtering precision
由于惯导系统( lsins )的误差方程是发散的，某些初始状态的误差会引起误差的漂移和积累，当观测量只有位置误差时，卡尔曼滤波的收敛速度很慢，某些状态(如方位角)误差很大，而以上除惯导外的其它导航传感器直接提供的只是位置信息，为了改善滤波器性能，本文根据里程计等传感器的特点，提出了首先对状态做出估计，然后在状态估计的基础上，进行卡尔曼滤波的方法。
