Autopilot and trackpilot
The data sentences to be sent to the Autopilot and trackpilot are selected in the application
Sensor Monitor.
When a route is active and the option Track steering or Autopilot is activated, the ECDIS
regularly sends the selected sentences to the autopilot or trackpilot.
Checkout before the TCS activation:
•
valid GPS, GYRO and LOG .
•
difference between HDG and active leg course .
•
ship should be within XTD limit and some distance in front of wheel over line .
Trackpilot option
Right click in the Autopilot console and select the item TCS options to display the dialog (see
Ú
Note:
To make the Autopilot console visible, tick on Autopilot in the Console tab of the
Options dialog.

Steering parameters
Velocity to come back to the track
The parameter controls how fast the ship comes back to the track. The yellow point
displayed on the route is the point the ship tries to reach. Bigger is the value, faster the ship
will try to get back on the route but more intensive will be the rudder usage when the ship is
sailing along the track.
CTS speed limit
It is the maximum of course change per second that the TCS can accept. Is not used anymore
for TCS, but can be used as reference to control ROT limit and in simulation mode.
Steering accuracy, degr
The parameter has influence on the rudder usage. The meaning is the minimum deviation
from the current leg course, which is ignored . Used only on straight part of the route.
Maximum radius, NM
It is the limit for maximum turning radius that used to check planned route against the ship
dynamics
Minimum radius, NM
It is the limit for maximum turning radius that used to check planned route against the ship
dynamics
