Flying an Automatic Mission, Calibration and Additional Tips

To fly an automatic mission in Cell Tower Scan you will first need to calibrate the center of the tower. The calibration mission is extremely important due to the close proximity at which such missions are flown. It allows to simultaneously account for the following errors.

  • Error in placing the center of the tower on the map during the tower
    generation process.
  • The drone GPS shift.

The calibration mission amounts to flying the drone above the center of the tower. You can do this manually, or by using another Drone Harmony mission. Once the drone is above the tower and the calibration run is underway, the user is asked to use the sticks to position the drone as accurately as possible above the tower center and press the C1/C2 buttons to record the position. Grid lines help the user locate the center.

The user is then presented with an image taken from the drone camera and can approve the calibration run, or re-run it. Once the calibration is approved, Drone Harmony automatically adjusts the positions of both the scene and the missions accordingly and the user is then able to start flying an automatic mission. There is no need to land the drone before starting the mission. It is important that the drone camera is facing downward (gimbal angle 90 degrees) during the calibration run.

Apart for the need in calibration, flying a Cell Tower Scan mission is identical to flying any other Drone Harmony mission.

Additional Tips for Flying Cell Towers

  • Set an action for the situation in which Radio signal is lost. Letting the drone hover in place, or continue the mission are the options you have.
  • Understand the level of both Radio and GPS interference around your tower before planning a very close-range mission. You can do this by planning a far mission and observing the interference when the drone is passing in front of antennas.
