A flight plan often contains places where the drone has to turn in an overall small confined area. If this situation is combined with a rather high global mission speed the yaw will change quickly at this location. This might be entirely fine for photo missions, but not so for video missions: Instead of getting nice panoramic footage the camera (i.e. the drone) will turn too quickly leading to a footage the human eye can not properly follow. The same argument holds for a rather large gimbal change along a small flight distance.

An example of a quick yaw change: The first waypoint has here a yaw oriented towards the left.

On the next waypoint the yaw is oriented towards the right, thus the drone has to turn almost 180° on a very small distance between the waypoints. To account for this, Drone Harmonys Flight Planner will automatically reduce the speed in this part of the flight.

Traditionally flight planning software offers the user to set a global mission speed, this is the speed the drone cannot exceed throughout the whole mission. Additionally on-board software controls how the drone has to accelerate and decelerate in order to follow the flight path given as a sequence of waypoints in space. Yet the fact that sudden gimbal and yaw  changes should also be considered to determine a proper speed for the drone is forgotten.

Harmonys Flight Planner is now taking into account how quickly gimbal and yaw are changing along a flight path. Whenever the user wants to record a video, it offers to automatically (and locally) reduce the flight speed whenever the gimbal and yaw change would be too fast for a smooth video footage. This feature contributes to our efforts to provide drone pilots with a software tool for professional aerial cinematography.
