Set Take-off point altitude
If the drift barometer sensor on the vehicle has reached a certain threshold, UgCS can request information on current altitude of the vehicle.
The same can occur when data from barometer sensor is reset (for example, restarting the vehicle).
In this case following error will be displayed in vehicle log: Route upload failed. Command cannot be sent: please specify take-off point altitude for the drone.
Following window will appear:
Click to set value from the current terrain altitude under the vehicle
