Gyrocompass System Description :
Gyrocompass System
A gyrocompass detects the direction of true north by means of a fast-spinning rotor, which is suspended with no friction and is influenced by gravity and rotation of the Earth. A gyrocompass consequently indicates a ship's heading. The ship's heading is transmitted to repeater compasses and other ship's equipment after the signal format is converted to serial data or to stepper or analog signals depending on what type of format the equipment requires.
There are three models in the CMZ900 series:
CMZ900B: Single-unit model, suitable for small vessels
CMZ900S: Single-unit model, suitable for all types of merchant vessels
CMZ900D: Dual-unit model for extra reliability
GYROCOMPASS CMZ-900B series
Features
- The system configuration can easily be adapted to each vessel's specifications.
- IEC 61162-2 high-speed code is available for the heading and rate of turn (ROT) outputs.
- A unique anti-vibration system enhanced by the velocity damping effect of high viscous oil, provides superior damping of vibration and decoupling of shock at sea.
- A small and lightweight container enhances the follow up speed. The gyrocompass changes smoothly and does not lag when a small vessel rapidly changes course.
- A space-saving design: the master compass can be installed on the autopilot stand.
-
The restart time can be preset from 1 to 99 hours.

System Configuration of CMZ900B
Explanation of Units (Basic configuration): CMZ900B type
1) Master Compass MKM026
The master compass consists of a control unit, container unit, and anti-vibration mechanism.
A gyrosphere, the key component of north seeking, is suspended in the container unit.
2) C.Operation Unit MKR040 (Optional)
The C.Operation unit receives the ship's speed and position data, and then corrects the speed error of the ship's heading signal.
3) AC Adapter MKR027 (Optional)
Since the master compass works on DC power, an AC adapter is used when AC power is supplied.
Thus, a two-way power supply can be easily achieved if needed.

-
A space-saving design: the master compass and the control box can be installed on the autopilot stand.
-
Automatic speed error correction is possible if both the ship's speed signal from the speed log and the latitude signal from a GPS or some other positioning device is available. Further, the latitude can be estimated from the ship's speed and the gyrocompass reading if the positioning device signal is absent.
-
An external heading signal from an instrument such as a magnetic compass or a GPS compass can be passed to repeater compasses and other ship equipment for back-up purposes.
-
As a standard function, a built-in monitor detects deviations between the master compass and external sensor heading readings.
-
The restart time can be preset from 1 to 99 hours.

2) Control Box MKC326
The control box consists of a power supply unit, control unit, and computing unit engaged in speed error correction of the ship's heading signal.
The control box amplifies heading signals coming from the master compass.
The amplified heading signals are distributed to repeater compasses and other ship's equipment depending on what type of format the equipment requires.
