Is there a way to change the starting heading in SITL? I’ve got the changing of take-off coordinates all sorted out, but being able to change heading would be useful as well.
You could specify the heading when you add the model in the world here https://github.com/PX4/sitl_gazebo/blob/22df9475ca0d157e2db066a20f64c35906bf7f25/worlds/standard_vtol.world#L13 .
You can specify the model position with
<pose>x y z roll pitch yaw</pose>
