Installation Parameters
The Installation Parameters pages allow you to define the relationship between the physical locations of the various sensors and the transducer. All relevant system units and sensors must be defined with their physical offset values in relation to the defined Ship Origin in the vessel’s coordinate system. You will only need to define these installation parameters once.
Prerequisites
This page is not available when in Replay mode.
How to open
The installation parameter pages are located in the Installation dialog box. On the Setup menu select Installation. To open a page, select Installation Parameters and then the relevant page.

Description
The physical location and installation angles (rotation) of each sensor must be defined 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. The physical dimensions and offset values are all required to allow the ME70 system to give you as accurate information as possible. The degree of accuracy offered by the ME70 system is directly related to the accuracy of the information you enter on the Installation Parameters pages. If you want to use the ME70 system for scientific research, a high degree of accuracy is strongly recommended. The relevant dimensions and offset values can normally be taken from the vessel drawings, in particular when using ME70 with the Bathymetric Option.
Installation Parameters contains a number of pages.
•  Ship function
On the Ship page you define a specific reference point (Ship Origin or origo) for the various sensor connected to the ME70 system. The origin is the common reference point where all three axis in the vessel coordinate system meet. All physical locations of the vessel’s sensors (radar and positioning system antennas, echo sounder and sonar transducers, motion reference units, etc.) are referenced to the origin.
•  Transducer function
Use the Transducer page to define the physical location of the transducer in the vessel coordinate system, as well as the installation angles (rotation). The installation angles define in which direction the transducer face points.
•  MRU (Motion Reference Unit)
Use the MRU (Motion Reference Unit) page to insert the physical location of the motion reference sensor (MRU) with reference to the vessel coordinate system.
