The Smart Return to Home is a great foolproof feature that enables ANAFI to automatically return to its takeoff point.
This innovative feature is used in three situations: manually, if the drone and controller lose connection and when the drone’s battery is running low.
In the center of Parrot Skycontroller 3, there is a button with a home icon, when you press this button ANAFI automatically returns to its takeoff point. For example, if your drone is no longer in your visual line of sight, press the button to have it return to its original takeoff position.
Loss of connection
If you’re in an area with many interferences or if you reach the maximum transmission range, your drone and controller may temporarily lose connection. In this case, the Smart RTH will automatically bring your drone to its original takeoff position.
Low battery life
If ANAFI’s battery life is running low, the drone automatically returns to the takeoff position.
ANAFI calculates its trajectory depending on the distance, the remaining battery level and the wind. It is possible to prevent ANAFI from returning automatically if you do not deem it necessary.
Thanks to this innovative feature, your drone will always find its way ‘home’.
How the Smart RTH feature works
Smart RTH uses advanced artificial intelligence to calculate the duration of the journey home. When the drone takes off, it saves the exact GPS coordinates of the takeoff position, during all the flight the drone calculate if it has enough battery to go back to the “Home”. If ANAFI reaches the minimum battery level needed to come back it will automatically return to the Home point.*
If you’re using the Follow Me mode, the drone will automatically return to the pilot’s current GPS location.
Note: The exact position of “Home” is always visible on the map in FreeFlight 6.
*The takeoff location is saved when the GPS signal is strong. Before taking off make sure GPS icon is green in FreeFlight 6.
Altitude of RTH
In the app, a RTH altitude of 30 meters is set by default, but you can modify this altitude between 20 and 100 meters.
To make sure your drone returns to its takeoff point safe and sound, we’ve set the RTH altitude at 30 meters. We chose this specific altitude, as we felt it prevent the drone from bumping into any obstacles. If you’re flying under this limit, ANAFI will automatically increase its altitude before making its way back.
If you are in the mountains or in a hilly environment, it’s a good idea to increase the RTH altitude. In the Safety settings, you have the option of changing between 20 and 100 meters.
The Geofence feature in FreeFlight 6 lets you create a confined flight perimeter by defining a maximum altitude and distance for your drone. It creates a virtual wall which cannot be crossed by the drone.
The Geofence perimeter is highlighted in a different color on the map, helping you visualize your location.
You can set the maximum altitude and distance of the Geofence by accessing the Safety settings in FreeFlight 6.
You can opt for a maximum altitude of 2 to 150 meters and a maximum distance of 10 meters to 1.2 miles/2 km from the take-off point.
Please note that the distance perimeter in Geofence is not automatically activated, whereas the altitude fence is always on. In any case, the drone cannot fly above an altitude of 150 meters. If you’d like to use the Geofence feature on both the distance and altitude, you have to activate it manually in the settings.
If you have activated Geofence, once you reach the maximum distance, the drone will stop at the virtual wall and you’ll receive an alert warning you.
If you’re in the process of executing a Smartdronie with the Geofence activated, and your drone reaches its maximum distance and/or altitude, it will automatically stop, and wait for new instructions.
Note: If you don’t have a GPS connection then the Geofence feature will not work. Once the GPS is fixed, the home point will be the first GPS fix location and not the take-off point. To ensure the best flight, please make sure the GPS is connected before take-off.
