12 Provide the accurate physical location of the sensor (or its antenna) with reference to
the vessel’s coordinate system.
The position of certain sensors must be defined as an offset to the Ship Origin in the
coordinate system to maximize performance. These offset values are all required to
allow the ST90 system to give you as accurate information as possible. The degree
of accuracy offered by the ST90 system is directly related to the accuracy of the
information you enter on the
Sensor Installation
page.
a 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.
b 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.
c 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.
13 Select

to save the new sensor interface you have defined.
The sensor interface is added to the
Installed Sensors
list on the
Sensor Installation
page.
14 At the bottom of the dialog box, select

15 Continue your work in the
Installation
dialog box, or select

Configuring the sensor interface
With multiple sensors connected to the ST90 system, many of them will provide the same
datagrams. We cannot expect that these datagrams provide the same information. The
Sensor Configuration
page allows you to define a datagram priority, so that the information
from the "most reliable" sensor is used by the ST90 system. You can also define manual
values in case a sensor is unserviceable, or not installed.
