YDK Tech CMZ900 Series of Gyro Compasses: Precision Navigation for Modern Vessels

Advanced Navigation Technology Complying with IMO Standards

The YDK Tech (previously Yokogawa) CMZ900 Series of Gyro Compasses offers several models to provide the right feature set to meet the needs of various vessels. All models have been type-approved to comply with IMO standards resolution and JIS-F9602 Class A standards. A gyro compass detects the true north by means of a fast-spinning rotor, which is suspended with no friction and is influenced by gravity and the rotation of the Earth. Consequently, a gyro compass indicates a ship’s heading. 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.

CMZ900-D Dual Gyro Compass

The CMZ900-D Dual Gyro Compass comes with a control box and a dual AC adaptor, offering a highly reliable dual system with switch-over controls, multiple signal outputs, and enhanced integration.

What’s Inside the Box

• 2 Master compasses
• 2 Master operation units with gyro heading indicator and alarm panel (built-in master compass)
• 2 Switch units (power switch unit, built-in master compass)
• 1 Control box
• 1 C. operation unit (built-in control box)
• 2 Gyro spheres
• 1 Dual AC adapter
• Standard spare parts
• Installation kit
• Spare supporting liquid
• Final drawings (3 sets)
• User manuals (3 sets)

Optional Instruments for Enhanced System Capability

Optional instruments are available to increase the signal outputs of the gyro compass. Other navigation equipment, such as repeater compasses and course recorders, are available as part of the system. The MASTER COMPASS (MKM 026) runs on a 24 VDC power supply. It is easily adaptable to power supply requirements, and all signal outputs can be maintained during AC power interruptions if a 24 VDC supply is provided. Serial data output IEC 61162-1 or -2 (high-speed transmission) is selective and contains the ship’s heading and rate of turn (ROT) information.

Key Features of the CMZ900 Series

• Modular design saves space
• Master Compass can be included in autopilot steering units
• Serial data output for heading and ROT output
• Manual and auto speed correction (900S & 900D models)
• Unique anti-vibration system
• Small, lightweight container enhances follow-up speed

In conclusion, the YDK Tech CMZ900 Series of Gyro Compasses represents a significant advancement in maritime navigation technology. With compliance to rigorous standards and a host of features designed to improve accuracy and reliability, these gyro compasses are an excellent choice for modern vessels seeking precision navigation solutions. The dual system ensures redundancy and reliability, while the modular design and optional instruments provide flexibility and scalability to meet diverse operational needs. Whether for large commercial vessels or specialized maritime operations, the CMZ900 Series delivers unparalleled performance and durability.
