摘　　要：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。用圆锥和划船补偿算法以及动态校准零位方法 ,来提高整个装置的精度和稳定性。该装置体积小、成本低、可靠性高 ,可广泛应用于民用和军事领域。Angular velocity and acceleration of the body are sensed using piezoelectric gyroscope and quartz accelerometer in a small inertial measure unit (IMU). Using the algorithm of corning for attitude updating and sculling for velocity updating and the method of dynamic base zero correction improves precision and stability of the IMU which may be applied in civil and military zones since its advantages of small volume,low cost and good reliability.
