•
First, input the actual roll and pitch angles of the vessel. A positive vessel angle is from
the red to the green co-ordinate system or:
¾
Positive pitch angle if the bow is up.
¾
Positive roll angle if the starboard (right) side facing downward.
•
Secondly, input the MRU mounting angle in yaw (positive clockwise). The yaw angle is
found by projecting the MRU +R arrow to the horizontal plane. The yaw angle is then the
angle between the longitudinal axis of the ship and the proR arrow in the
horizontal plane. It is important that this angle is measured accurately and input correctly
to avoid degradation in the performance of the roll and pitch measurements from the
MRU.
Note
Before starting the Auto Mount process, be sure that the ship motion has
stabilised and that the harbour conditions are calm.

Then click
Next
to start the Auto Mount process. The window in Figure 52 will appear,
and the MRU offset angles are computed. A time-out bar shows the progress. When
finished and the found mounting angles look OK, press
Finish
.
Note
The new MRU mounting angles are only valid in the Seapath after download of
parameters.
