The inertial measurement unit is a device that measures the three-axis attitude angle (or angular rate) of the object and the acceleration. In general, an IMU includes three single-axis accelerometers and three single-axis gyros. The accelerometer detects an acceleration signal of an independent three-axis of the object in the carrier coordinate system, and the gyro detects the angular velocity signal of the carrier relative to the navigation coordinate system. The angular velocity and acceleration of the object in three-dimensional space are measured, and the posture of the object is calculated. It has important application value in navigation.
