5.3.2 Orientation

Figure 78: MOTION Settings Wizard - Orientation

This dialog specifies the orientation of the F180R System IMU in the vessel frame of reference.

It is important that the F180R System IMU orientation in relation to the vessel frame is

accurately measured and input. Any unaccounted-for offset between the vessel's heading

and the F180R System's longitudinal axis results in "crosstalk" between pitch and roll; that is,

some of the movement that should correctly be interpreted as changes in pitch are

interpreted as roll, and vice versa. Even a small discrepancy between the vessel and F180R

System IMU orientations can result in serious errors due to crosstalk.

There are some standard configuration parameters suggested in MOTION Control that can be

accessed from the Connector and X Axis drop down, the system image on the right will help

you visualising the orientation.

If your F180R System IMU has any other orientation click the Advanced button and tick the

Make changes to Standard Orientation on Next Page checkbox to specify offsets from the

chosen standard orientation in the next step.

NOTE: The angular offsets can be updated later after the results of an alignment

procedure such as a multi-beam patch test.

5.3.3 Advanced Orientation

This setup step will only be displayed if you have tick the Make changes to Standard

Orientation on Next Page checkbox in the Orientation step of the wizard.
