1. PRINCIPLE OF THE AUTOPILOT
Principle of Operation
In the AUTO modes, the heading information from an associated sensor is continuously compared with the set course (in the NAV mode, the course to the waypoint set on the plotter connected). With the boat on course, the two signals are equal.
If the boat goes off course, the difference between the primary heading and the set course will change proportionally and there will be an imbalance at the comparator, whose output will move up or down depending on whether the course error is to the left or right of the set course.
The rudder continues to move until a balanced condition is obtained at the comparator, at which point the drive switches off.
To set the rudder when the boat is
