Inertial Measurement Unit
- Formal
-
An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes, sometimes also magnetometers.
- Practical
-
A MEMS module which measures angular velocity and linear acceleration using an accelerometer triad and an angular rate sensor triad. Other IMU sensors may include magnetometers and pressure sensors.
