GYROCOMPASS
YDK CMZ900D

Gyrocompass detects the ship’s heading.

It detects the direction of true north by using a fast-spinning rotor, which is influenced by gravity and rotation of the Earth, and detects ship’s heading. The heading indicated by the gyrocompass is transmitted to receiving devices, including the repeater compass. 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. The CMZ900 series gyrocompass provides the following three types of gyrocompass system:

  • CMZ900D: Using dual gyrocompass, it is suitable for general merchant vessels
  • CMZ900S: Using single gyrocompass, it is suitable for general merchant vessels
  • CMZ900B (B2): a standalone gyrocompass for small merchant vessels
Product Information
Description

 

  • System configuration can be easily adapted to each vessel’s specifications
  • Supports IEC 61162-2 high-speed code for heading and rate of turn (ROT) outputs
  • Unique anti-vibration system, enhanced by high viscous oil damping, provides excellent vibration suppression and shock decoupling at sea
  • Compact and lightweight design improves follow-up speed, ensuring smooth course adjustments without lag during rapid course changes on small vessels
  • Space-saving design: both the master compass and control box can be installed on the autopilot stand
  • Automatic speed error correction is possible with input from the ship’s speed log and GPS (or other positioning devices). If the GPS signal is unavailable, latitude can be estimated from the ship’s speed and gyrocompass readings
  • External heading signals from instruments such as a magnetic compass or GPS compass can be transmitted to repeater compasses and other ship equipment for backup
  • Mechanical and software-controlled switchover are available to select the master compass for enhanced reliability
  • Built-in monitor detects deviations between the master compass and external sensor readings as a standard function
  • Preset restart time from 1 to 99 hours for operational flexibility
