The yaw property of a gimbal rotation operation, how much the gimbal rotates on the yaw axis. When the rotation mode is DJIGimbalRotationModeAbsoluteAngle, the yaw value is relative to the aircraft's heading. When it is nil, no operation will be applied to the yaw axis.
The angle value, when the gimbal is rotating, relative to the current angle.
The angle value, when the gimbal is rotating, relative to 0 degrees (aircraft heading). For Inspire 1, using X3, X3 Zoom and Z3 cameras will be relative to true north. Using X5, XT and X5R will be relative to the aircraft heading. For Inspire 2, using X4S and X5S cameras will be relative to true north. Using X7 and Z30 will be relative to the aircraft heading. For Matrice 300 RTK with H20 series and Zenmuse P1 camera, the angle rotation is relative to the aircraft heading if you rotate the gimbal directly. The angle rotation is relative to true North if you use it in WaypointV2MissionAction.
Rotate the gimbal's pitch, roll, and yaw in SPEED Mode. The direction can either be set to clockwise or counter-clockwise. For Phantom 3 Professional, Phantom 3 Advanced and Phantom 3 Standard, roll and yaw rotations are not available. For Inspire 1, Inspire Pro and M100, pitch, roll and yaw rotations are available. For Osmo, roll rotation is not available. The yaw angleVelocity of DJIGimbalSpeedRotation range is (-120, 120).
