18-27 Section 18 Setting up the Operation Mode
Setting Item Description of Setting Setting Value
Tracking Gain Set up the tracking gain. This can be set up even during
automatic sailing.
The tracking gain value specifies how quickly the ship
will return to the original course when it has deviated
from the course.
You can select from three tracking gain settings of
[High], [Middle] and [Low].
For example, assume that the target gain value is being
set to "16 deg./NM" and the own ship is positioned at 1
NM right of the tracking gain.
In this case, specify the distance for the own ship to
approach the target at an angle of 16°.
If the distance between the own ship and the target
course is shortened, this angle will also be reduced.
When the own ship has reached the target course, the
angle will be the same as WP1 viewed from 0 of a
WPT, and the more the LD will be, the larger this angle
will get.
Note that you may lose the control of the helm
depending on the tracking gain value, so be careful with
the setting.

Drift Correction Set up the drift correction. This can be set up even
during automatic sailing.
When this is set to On (High/Middle/Low), control is
performed considering the tide if the own ship's speed
is 5 knots or faster.
None: Off (Drift correction will not be performed.)
High: Drift correction will be performed. The drift
correction value is equivalent to the tidal vector
(100%).
Middle: Drift correction will be performed. The drift
correction value is 2/3 of the tidal vector.
Low: Drift correction will be performed. The drift
correction value is 1/3 of the tidal vector.
