An IMU sensor is a digital device that measures and records an Unmanned Aerial Vehicles’s acceleration, angular rate, and orientation in order to maneuver it. The IMU uses a conflation of accelerometers, gyroscopes, and magnetometers to achieve the measuring process. Recent developments in this area has allowed for IMU-enabled GPS (Global Positioning System) devices as well. This lets us use GPS equipment even though GPS-signals are not available.
