Note
Providing the correct value for this rotation is crucial for the sonar performance.
An inaccurate or incorrect value will cause the sonar echoes to be presented at the
wrong bearing.
Use the
Transducer
page to define the physical location of the transducer in the vessel
coordinate system, as well as the installation angles (rotation). Do this as accurately as
possible.
Motion sensor
The physical rotation of the motion reference unit (MRU) relative to the transducer is
required to allow the MF90 system to adjust for roll and pitch as accurately as possible.
Note
Correct values for motion sensor rotation are critical for the sonar performance.
Use the
MRU
(Motion Reference Unit) page to insert the physical location and rotation
of the motion reference sensor (MRU) with reference to the vessel coordinate system.
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. These pages are located in the
Installation
dialog box.

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 MF90 system hardware units are installed as specified in this manual.
• The MF90 system is turned on and operates normally.
• The MF90 system is in Normal mode, but
TX Power
is set to Off to prevent transmissions.
