Robertson AP45 Autopilot

 

Operation

Steering by bearing to waypoint (CTS)

For some navigational receivers, bearing to a waypoint or course to steer is used as the steering information.

If a satellite navigator is used, it should have compass and log input to ensure proper dead reckoning between each fix.

1.Set the navigation receiver to calculate bearing to a waypoint from present position.

2.Select AUTO-mode on the AP45, and set the course selector knob to the bearing showed on the navigation receiver.

3.Select NAV-mode. The output signals from the navigation receiver will correct the course to steer to make the vessel steer towards the waypoint.

The Information display shows time since last update and the amount of course change in degrees, while the course display shows the new course to steer.

08 MIN CHG:05°

NAVIGATION

1.If the corrections from the navigation receiver initiates a course change greater than 10 degrees, the autopilot alarm is activated and the course change has to be acknowledged using the ALARM RESET button.

A typical sailing situation is illustrated in figure below.
