Product Description
ComNav 1440 & 1460 Autopilot Systems
are reliable, accurate and easy to use
aids to navigation. They feature four
operating modes, watertight design, and
a built-in navigation interface.
When steering along a Course line in NAV
MODE, the 1440/1460 use Heading
information from the compass, and
position information from a a GPS
receiver, a chartplotter, or other device, to
calculate a Course to Steer which will
keep the vessel on the Course line.
The four operating modes are:•S
TANDBY MODE allows manual
steering while displaying compass
information. 1440/1460 Autopilots have a feature
called Ghost Rudder. Should the Rudder
Feedback ever fail, the Autopilot will use
its prior knowledge of how the rudder
moves to calculate new “virtual rudder”
positions. While the Ghost Rudder will
not allow the Autopilot to steer as well as
it can with the Rudder Feedback, it will
allow the Autopilot to be used until repairs
can be made.
•POWER STEERING MODE features push
button steering control, and displays
compass or rudder information.
•PILOT MODE steers to a constant
Heading.
•NAV MODE steers along a Course line,
when the 1440/1460 is connected to
an appropriate navigation device.
A Dodge feature is available in both PILOT
and NAV MODES. 1440/1460 Autopilots are protected
against many mishaps, including: reverse
power connection, output circuitry
overload, computer failure, or program
error.
To steer a constant Heading, the
1440/1460 Autopilot compares the
current Compass reading to the Heading
(Course) that the operator has selected.
If the vessel is not on the correct
Heading, the Autopilot calculates the
rudder position which will bring the vessel
onto the correct Heading.

1440 Control: 5.1 x 2.75 x 1.0 inches
The Autopilot uses the vessel’s steering
system (a hydraulic system, or an electric
motor, and mechanical linkage) to move
the rudder (or outboard motor) to the
position it calculates. Information from
the Rotary Feedback (or Outboard
Feedback) is used to calculate new
rudder positions, and to verify that the
steering system has followed the
Autopilot commands.
