YDK Tech (previously Yokogawa) CMZ900 Series Gyro Compasses: Precision Navigation for Every Vessel

Comprehensive Features and Compliance

The YDK Tech CMZ900 Series of Gyro Compasses offers several models to meet the diverse needs of different vessels. All models have been type-approved to comply with IMO standards resolution A.424(XI) and JIS-F9602 Class A standards, ensuring high reliability and precision.

Understanding the Gyro Compass

A gyro compass detects the true north by means of a fast-spinning rotor, which is suspended without friction and influenced by gravity and the Earth’s rotation. This advanced technology allows the gyro compass to indicate a ship’s heading accurately, making it an essential tool for maritime navigation.

CMZ900 Series Compliance and Standards

The CMZ900 series has been type-approved in accordance with International Maritime Organization (IMO) standards, resolution A.424(XI), as well as JIS-F9602, Class A standards. This compliance guarantees that the compasses meet the highest standards of safety and performance.

CMZ900-B2 Gyro Compass for Small Vessels

The CMZ900-B2 Gyro Compass is specifically designed for small vessels, providing smooth gyro changes without lag even when the vessel changes course rapidly. This model ensures precise navigation and enhances safety at sea.

Technical Specifications

The system configuration of the CMZ900 series can be easily adapted to the specific requirements of different vessels. It supports IEC 61162-2 high-speed code for heading and rate of turn (ROT) outputs. Additionally, it features a unique anti-vibration system enhanced by the velocity damping effect of high viscous oil, which provides superior damping of vibration and decoupling of shock at sea.

Adaptable System Configuration

The CMZ900 series is designed to be versatile and adaptable. Its small and lightweight container enhances follow-up speed, ensuring that the gyro compass changes smoothly without lag, even during rapid course changes.

Space-Saving Design

The compact design allows the master compass to be installed on the autopilot stand, saving valuable space on the bridge. This design consideration makes it ideal for vessels with limited installation space.

Restart Time

The restart time of the CMZ900 series can be preset from 1 to 99 hours, offering flexibility and convenience to operators.

Bridge Alert Management System (BAMS) Interface

The CMZ900 series includes a Bridge Alert Management System (BAMS) interface function based on IEC62288 Ed. 2, ensuring enhanced safety and compliance with modern maritime standards.

Settling Time and Accuracy

The CMZ900 series reaches operational state within 5 hours, with a typical settling time of about 2 hours. Its accuracy is impressive, with static accuracy of +/- 0.25 degrees x sec and dynamic accuracy of +/- 0.7 degrees x sec. The follow-up accuracy is 0.1 degrees or less, ensuring reliable performance.

Power Supply

The main power supply for the CMZ900 series is 24 V DC. Additionally, an AC adapter (optional), type MKS070, is available for 100V/110V/115V/220V/AC 50/60Hz single-phase power, providing flexibility for different vessel power systems.

Conclusion

The YDK Tech CMZ900 Series of Gyro Compasses is a reliable and precise navigation tool, designed to meet the rigorous standards of modern maritime operations. Its compliance with IMO and JIS standards, adaptable system configuration, and advanced features make it an excellent choice for ensuring safe and accurate navigation for vessels of all sizes.
