Compass Calibration

After calibrating the accelerometer, the wizard takes us to the compass calibration. To begin calibration, click on "LIVE CALIBRATION" (below photo).

A dialogue box will display showing several axis and white dots (targets) surrounding the different axis (above photo). To calibrate the compass the quadcopter must be turned in a circular motion as follows; right side up, left side up, right side up, nose down, nose up, upside down. By rotating the quadcopter in these positions, you should hit each of the white dots, which is the intention of the exercise (below photo). Once all of the white dots have been hit keep rotating the vehicle in the different positions until the auto-accept informs you that the calibration is finished or if it seems as though the auto-accept is taking far too long, you can also click on the DONE button.

If the calibration is successful, a window will display showing the "NEW MAG OFFSETS", click OK for both windows (above photo). Then click the NEXT button to move on to the battery monitor configuration.

Battery Monitor Configuration

Mission Planner Battery Monitor Configuration

For the BATTERY MONITOR configuration we will pick Pixhawk as the autopilot version, 3DR Power Module as the sensor and 5200 as our battery size. Note: For the battery size enter the battery size that you are using. Once these selections have been made click NEXT.

Sonar Configuration

For the sonar configuration we will just click NEXT, since we are not using this optional module in our build. Once we click the NEXT button we will begin the radio calibration.
