Figure 36: Depth Gates, With No Roll
Figure 37 shows the same bottom image with a small roll value to port. Notice that the
ends of the swath have been cut off due to the action of the static depth gates (no
motion sensor applied). In this figure, and all remaining figures in this discussion, the
bottom is flat.
Figure 37: Depth Gates, With Roll
When controlled by a motion sensor, the depth gates will be parallel to the local
horizontal plane of the earth even as the vessel rolls.
Figure 38 shows the same bottom
image with dynamic depth gates applied.
