What is An IMU?

An IMU includes three accelerometer of single shaft and single axis of gyroscope and accelerometer to detect objects in the vehicle coordinate system independent triaxial acceleration signal, and relative to the navigation coordinate system of the angular velocity gyroscope detection carrier signal, measuring angular velocity and acceleration of objects in three-dimensional space, calculated and objects. It has a very important application value in navigation. Additional sensors can also be fitted to each shaft for increased reliability. Generally, the IMU is mounted on the center of gravity of the object under test.

IMUs are mostly used in devices that require motion control, such as cars and robots. It is also used in the application of precision displacement calculation with attitude, such as inertial navigation equipment of submarine, aircraft, missile and spacecraft, etc.
