Mk 27 GYROCOMPASS SYSTEM
The Mk 27 gyrocompass is primarily a direct
reading
compass.
This
compass
seeks
and
continuously indicates the bearing or true north. This
gyrocompass consists of three major components:
master unit, control cabinet, and power converter, as
depicted in figure 4-3. Optional equipment includes a
switching unit and a speed compensator. The Mk 27
gyrocompass can be configured to provide heading
information to a remote area with a step transmitter,
1X or 36X synchro data transmitter, or a combination
of these units.
AN/WSN-2 STABILIZED
GYROCOMPASS SET
The AN/WSN-2 stabilized gyrocompass, shown in
figure 4-4, seeks and continuously indicates the
meridian and zenith. The AN/WSN-2 provides precise
output signals for ship’s heading, roll, and pitch. The
set uses an accelerometer-controlled, three-axis, gyro-
stabilized platform to produce vital heading synchro
data and reference, nonvital heading synchro data,
and both roll and pitch angle synchro data. The
AN/WSN-2 stabilized gyrocompass consists of five
major components: inertial measuring unit, control
indicator, control power supply, amplifier synchro
signal, and battery set.
The AN/WSN-2 provides the following output
signals: heading vital and nonvital (1X, 36X 400HZ
synchro), roll and pitch (2X, 36X400 Hz synchro), and
remote alarm.
