Improving the accuracy of angular resolution is the key way to improve the navigation parameter resolution precision of accelerometer based gyro-free inertial navigation system. 提高角速度解算精度是提高无陀螺惯性导航系统导航参数解算精度的主要途径。
Since angular velocity is calculated by apparent acceleration that is sensed through accelerometer on board, it is the basement to choose a reasonable method in order to improve the precision. 由于角速度是由载体上加速度计敏感出的比力解算出的,选择合理的方法解算角速度是提高其精度的根本。

The constant angular rate was applied to three axis of turntable at the same time to actuate dynamic error term of accelerometer. 在三轴转台的三个轴上同时施加恒定角速率,激励出加速度计动态误差项。
