X Offset
Select the offset value on the X axis (fore-and-aft direction) from the Ship
Origin . Adjust with a positive value for X if the sensor is located ahead of
the ship origin.
Y Offset
Select the offset value on the Y axis (athwartship) from the Ship Origin . Adjust
with a positive value for Y if the sensor is located on the starboard side of the
ship origin.
Z Offset
Select the offset value on the Z axis (vertical) from the Ship Origin . Adjust with
a positive value for Z if the sensor is located under the ship origin.
Rotation
For some sensors - typically motion sensors and transducers – the physical location of
the sensor is not sufficient to extract accurate data. These sensors are installed with
physical angles. These angles are often referred to as "installation angles" or "offset
angles". The sensor can be rotated around the three axis of the vessel coordinate
system.
• Rotation Around X(Roll)
• Rotation Around Y(Pitch)
• Rotation Around Z(Yaw)
In the user interface you will only need to specify the installation angles when the
parameters are shown.
Rotation Around X
Specify an angle (in degrees) to compensate for any deviation from the X axis
(fore-and-aft direction) in the vessel coordinate system.
Rotation Around Y
Specify an angle (in degrees) to compensate for any deviation from the Y axis
(athwartship direction) in the vessel coordinate system.
Rotation Around Z
Specify an angle (in degrees) to compensate for any deviation from the Z axis
(vertical direction) in the vessel coordinate system.
Add
When you have set the parameters for a new sensor interface, select
Add
to save
it. Once a sensor has been added to the ST90 system configuration, it appears in
the
Installed Sensors
list.
