Hi, I am cooperating in developing manned drones in South Korea.
During the flight test of the prototype we made, the same phenomenon as the attached video continues to occur(at 0:10~).
There is no problem with hovering in non-GPS mode, but in hovering (Loiter) mode where GPS is involved, sudden jittering is performed at the time of transition.
Any idea about this? Is it a problem unique to the large aircraft?
