QGroundControl will guide you to place and hold your vehicle in a number of orientations (you will be prompted when to move between positions).
This is similar to compass calibration except that host the vehicle still (rather than rotate it) in each orientation.
The calibration steps are:
- Start QGroundControl and connect the vehicle.
- Select the Gear icon (Vehicle Setup) in the top toolbar and then Sensors in the sidebar.
Click the Accelerometer sensor button.
You should already have set the Autopilot Orientation. If not, you can also set it here.
Click OK to start the calibration.
Position the vehicle as guided by the images on the screen. Once prompted (the orientation-image turns yellow) hold the vehicle still. Once the calibration is complete for the current orientation the associated image on the screen will turn green.
Repeat the calibration process for all vehicle orientations.
Once you've calibrated the vehicle in all the positions QGroundControl will display Calibration complete (all orientation images will be displayed in green and the progress bar will fill completely). You can then proceed to the next sensor.
