For this simulink block, the description of the fifth input is "Contains the gravity, in selected units." It does not specify the coordinate frame. I assume it means the gravity in body-fixed axes, right? Thanks,

Yes, the rest of the block accepts inputs in the form of body-fixed axes, so the gravity input should follow along the same lines.

What if the body itself is rotating？The gravity should be a changing vector with respect to the rotating?
