A Brief
The
Distribution
Box
is
the
heart
of
the
system
and
everything
Overview
connects
to
this.
It
contains
the
computer
section
that
reads
the
data
from
the
sensors,
i.e.
the
rudder
position
from
the
Rudder
Feedback
Unit,
the
vessel's
heading
from
the
Compass.
It
reads
the
helmsman’s
orders
from
the
Autopilot
Control
or
a
Navigator, then calculates, using the sea state and configuration
settings and moves the rudder, via the Drive Motor to maintain
a course.
