YDK (Yokogawa) CMZ900 Gyro Compass

YDK, formerly known as Yokogawa, introduces the CMZ900 Gyro Compass Series, a cutting-edge solution designed to enhance the precision and reliability of maritime navigation. With a range of models catering to diverse vessel needs, this series is poised to redefine navigation standards. All models are 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 rotation of the Earth. A gyro compass consequently indicates a ship’s heading. 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.

Different Gyro Model in CMZ900 Series:

• CMZ900-B2 Gyro Compass for small vessels (smooth gyro changes without lag when small vessel changes course)
• CMZ900-S Gyro Compass (+ Control Box with built-in monitor)- suitable for all merchant vessels, with various types of signal outputs
• CMZ900-D Dual Gyro Compass (+ Control Box + Dual AC Adaptor) – Highly reliable dual system,  switch-over controls, multiple signal outputs, & enhanced integration

MASTER COMPASS (MKM 026) runs on 24 VDC power supply. It is easily adopted to the power supply requirements, and all signal outputs can then be maintained during AC power interruption if 24 VDC 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.
