Waypoint turn types

UgCS desktop route planning allows specifying different turn types – i.e. the way the drone passes the waypoint.

There are 2 different route planning modes for DJI autopilots: fixed-point turn mode (Stop and Turn) and adaptive coordinated turn mode (Adaptive Bank Turn); 2 different turn types for Ardupilot vehicles: Straight waypoint and Spline waypoint and 1 turn type for PX4 autopilot - straight.

Turn typeSupported autopilotDescriptionNotes
Stop & TurnDJI AutopilotAircraft flies to the first fixed point accurately stop at the fixed point and then flies to the next fixed point.Works with all actions
Adaptive Bank TurnDJI AutopilotAircraft will not stop at the fixed point, but will “cut the corner” and pass through without a stop.
The maximum corner radius can be adjusted in UgCS for DJI mobile applications in “drone-specific settings”.
Doesn't work with Wait, Change yaw, Set camera altitude, Set camera mode, and Panorama actions.
StraightArdupilot, PX4The vehicle will fly straight to the location specified as a lat, lon, and altitude.
SplineArdupilotThe vehicle will fly to the location specified as a lat, lon, and altitude, but when executed the vehicle will fly smooth paths (both vertically and horizontally) instead of straight linesMake sure the line segment after the waypoint is long enough
otherwise autopilot can fly unexpectedly missing some waypoints. What is "long enough"? The desired
segment length varies with speed. Our tests show that with a ground speed of 5m/s route segment must be
at least 20m long. If the speed is set to 10m/s then the route segment after the waypoint should be at least
50 meters.

!!! Different turn types for fixed-wing vehicles are not supported.
