Inserting the ship origin and dimensions
When you have several different sensors and transducers on your vessel, and you wish each
of them to provide accurate data, you need to know their relative physical positions. To do
this, you must establish one or more common reference points. This reference point is also
used to position the sonar echoes relative to the ship symbol on the display presentation.
Prerequisites
The ST90 system has been set up with its hardware units connected as specified in the
Installation Manual .
• The ST90 system is turned on and operates normally.
• The ST90 system is in Normal mode, but
TX Power
is set to Off to prevent transmissions.
• The vessel is berthed or at sea.
• Neither tools nor instruments are required.
For accurate ship dimensions you need the detailed vessel drawings.
Context
On the
Ship
page you can use the ship's physical dimensions to create a virtual reference
point (the Shop Origin ) in a dedicated coordinate system for the ST90 system. The Ship
Origin is normally located in the following position:
•
X position
: Half the ship's length
•
Y position
: Half the ship's width
•
Z position
: On the waterline
