horizontal and/or vertical planes. We strongly recommend that you install your motion
reference unit so that all rotation angles can be set to 0 (zero).
The required accuracy of the offset and rotation angles depends on the accuracy requirements
for the echo data.
Tip
The motion sensor offset values are not important for sonar operation. Correct values for
motion sensor rotation are important for roll and pitch compensation.
Note
The Kongsberg Seapath
®
- and other GPS systems - allow you to define the MRU location in
the positioning system. If this is done, the MRU offset values in the ST90 system must be set
to 0 (zero) to avoid "dual compensation". The rotation angles are normally not recorded by
the positioning system. These can either be inserted into the MRU control application, or
into the ST90 system. Make sure that you do not insert them both places.
A
Rotation around the x-axis:
In the positive horizontal
direction (forward), a positive
rotation is clockwise.
B
Rotation around the y-axis:
In the positive horizontal
direction (starboard), a
positive rotation is clockwise.
C
Rotation around the z-axis: In
the positive vertical direction
(down), a positive rotation is clockwise.
D
Reference point (Ship Origin)
