Tip
It is common practice to place the Ship Origin at the same position as the motion
reference unit (MRU). This will minimize the vectors when your vessel is moving. Use
the vessel drawings to establish the offset values between the basic position of the Ship
Origin and the MRU location.
If you do not have a motion sensor you can place the Ship Origin at any location on the
vessel. We suggest that you place the origin under the captain's seat on the bridge. All
sensors will then be referenced to this position. Whenever a sonar is used with short
ranges, this will provide a more precise presentation.

Do this as accurately as possible. This information is used to create a new origin in
the vessel coordinate system.
6 Offset:
a If you want to keep the default reference point (origin), leave all offset values
to 0 (zero).
b If you want to move the reference point to another location, use the necessary
offset values.
To find these offset values, consult the vessel drawings. Do this as accurately
as possible.
