2.12 Navigating with the AP35
The AP35 has the capability to use steering information from an external
navigator (GPS, Chart Plotter) to direct the boat to a specific waypoint
location, or through a route of waypoints. In the NAV mode, the AP35 uses
the heading sensor as it's source of heading for course keeping. The steering
and speed information received from the external navigator alters the set
course to direct the AP35 to the destination waypoint.
Note ! Navigational steering must only be used in open waters. The process of
having an external navigation receiver direct an autopilot can be a slow
acting process. By selecting the NAV mode, the AP35 is set for automatic
steering on the current set course and then waits for the user to accept the
course change to the destination waypoint.
To obtain satisfactory navigation steering, the following points must be
fulfilled prior to entering the NAV mode:
The AP35 autosteering must be tested and found satisfactory.
The navigation receiver must be operating and the navigation system
(GPS, Chart Plotter) must be in full operating mode with adequate signal
characteristics for valid position and steering data.
At least one waypoint must be entered and selected as the current
waypoint in the navigation receiver.
The navigation source in the AP35 USER SETUP menu must be set for
the navigator that contains the current waypoint.
The AP35 is designed to steer in “mixed mode” operation. This combines
the straight steering capability of cross track error (XTE) steering in
conjunction with the turning capability of bearing mode steering (course to
steer (CTS)).
