(Android) How to prepare and start a free flight mission

Warning: The Free Flight Mission is recommended for advanced users to map more difficult objects (e.g. sides of houses, towers, pylons, bridges, etc). It requires to pilot the drone and to understand how to fly an optimal flight path.

To do a free flight mission:

Step 1. Prepare a free flight mission
Step 2. Start a free flight mission

Step 1. Prepare a free flight mission

1. Open the App.

2. In the home screen, click Free Flight Mission.
The Map View is loaded.

  • If you are connected to the Internet, a background map is displayed.
  • The mission can also be prepared in your office. The displayed map is cached in memory and will be available when starting the mission in an area without Internet connection as long as the App is not stopped.

3. (Optional) On the left of the screen, change the settings of your free flight (horizontal and vertical image spacing).

Note: By default the horizontal and vertical image spacing are set to 5 and 3 meters respectively. This is well suited to reconstruct an object at a distance of approximately 20m. It is recommended to choose the horizontal and vertical image spacing such as there is enough overlap between the images. For more information on optimal flight plans: 202557459.

4. Center the map on the area of interest by moving it.

  • The map view displays the current position of the drone. It allows to keep track of the mission.
  • When the drone reaches the mission altitude, check that the camera is pointing towards the area of interest. It can happen that the gimbal is not properly initialized and that the camera is not looking in the correct direction. The gimbal can be manually changed during flight by going to the camera view and pressing the down arrow. For more information about the camera view: 203873435.
