1.3.4 Track Control
The operating mode of track control presupposes the connection of an external naviga-
tion receiver (e.g. GPS) to the autopilot.
Within this system conception, the navigation receiver (for APA and APB telegram trans-
mission) transmits track section data of a planned route to the autopilot. Any track sec-
tion is indicated as a track course and executed in terms of control engineering.
If XTE telegram transmission is used, the operation will be different. First of all, the new
track course is to be read off the navigation receiver and to be adjusted on the
PILOTSTAR D via the rotary knob.
The following example shows a route consisting of 3 waypoints and 2 track sections.
Planning of such a route can only be made via the navigation receiver (see manufactur-
er’s handbook).
On reaching the WOP circle, the autopilot receives the track course preselection for the
next track section. This state is indicated via the text line and, after acknowledgement,
accepted as a new track course. At this moment, the ship starts turning with the prese-
lected rate of turn into the next track section.
