The IMU is embedded in the flight controller and includes a gyroscope and an accelerometer, which respectively produce angular rate (in degrees/second) and linear acceleration measurements (normalized to gravitational acceleration at sea level g = 9.81 m/s^2).

  1. Connect to the FC (https://ethidsc.atlassian.net/wiki/spaces/DTSKY/pages/2233466906/6.1+Setting+up+the+Flight+Controller#Connecting-to-the-Flight-Controller-(FC)%5BhardBreak%5D)

  2. Navigate to the “Setup” page

  3. Place the drone on a (very) flat surface

    1. Make sure the drone is level on the flat surface

  4. Click on “Calibrate Accelerometer”

    1. Do not move the drone while the calibration is in progress or it will invalidate the calibration

  5. Wait for a few seconds. A successful outcome will produce a “reset” of pitch and roll measurements and the rendering of the drone’s attitude will show a level condition. Moreover, a message will appear on the top left of the CleanFlight interface saying “Accelerometer calibration finished
