2.3 Inboard autopilot system
A typical inboard autopilot will consist of the items
shown:

SMART

1. Autopilot control head — This provides the
display and controls required to use the autopilot.
Multiple controllers can be added if required, for
example a controller at each helm position.
2. Course computer — This is the central intelligence
hub of the autopilot system, linking the control head
to the drive unit.
3. Drive unit — The drive unit interfaces with your
boat's steering system.
4. Fluxgate compass— The fluxgate compass
provides the autopilot with a magnetic heading
required for maintaining a course.
5. Rudder reference — Required for some systems
only. This provides feedback from the rudder and
can enhance steering performance.
Note: Hydraulic drive units should always use a
rudder reference transducer. If in any doubt please
contact Raymarine customer support.
In addition the autopilot may receive data from other
components, for example:
• Multifunction display — The autopilot can connect
to a compatible multifunction display. This provides
enhanced capabilities for creating and following
routes.
• GPS — Usually received from a multifunction display,
the autopilot uses position data when following routes
and calculating the optimum course to steer.
• Wind transducer — The autopilot can steer relative
to a specified wind angle.
