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 ME70 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 |
If you want to change the location of the Ship Origin, you can do this by providing offset values in the X, Y and/or Z directions. To do this you will need the ship drawings.
TipIt is common practice to place the Ship Origin at the same position as the motion reference unit (MRU). This will minimize the vectors when your vessel is moving. Use the vessel drawings to establish the offset values between the basic position of the Ship Origin and the MRU location.
Further requirements
You must proceed by defining the locations of the navigation system antenna, the motion reference sensor, and the transducer.
These locations are all referenced to the same reference point.
