angular velocity and acceleration of the body are sensed using piezoelectric gyroscope and quartz accelerometer in a small inertial measure unit (imu).
该装置用压电陀螺和石英挠性加速度计来测量载体的角速度和加速度。
above all, according to the fog and quartz accelerometer adopted in navigation system, the static error models of imu(inertial measurement units) are built up.
