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. 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 Viewing enhancement of the system capability, optional instruments are available in order to increase the signal outputs of the gyro compass. Other navigation equipment such as repeater compasses, course recorder are available as a part of the system. 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. Features Modular design saves space Master Compass can include in autopilot steering unit Serial data output for heading and ROT output Manual and auto speed correction (900S & 900D) Unique anti-vibration system Small, lightweight container enhances follow-up speed Tech Sheet(s) YDK (Yokogawa) CMZ900 Series Gyro Compass Datasheet Request more info on this product Request service for this product Related Products Anschütz Standard 22 NX Gyro Compass Anschütz Standard 22 Gyro Compass (End of Life) Simrad GC80/85 Gyro Compass MK2 YDK (Yokogawa) PT900 Autopilot Communication Entertainment Exterior Comms System GMDSS Interior Communication Systems Radios - Handheld Radios - Shipboard Inmarsat-C Solutions Satcom L-Band Broadband Satcom LEO High Performance Flat Panel Satcom VSAT (Ka) Satcom VSAT (Ku) Satcom Networking & Security Satellite Phones SatCom Accessories — Iridium — Inmarsat Satellite Airtime Partners Sound Reception Systems Weatherfax End of Life - Communication Navigation AIS AutoPilot / NPPU Autonomous Systems Chart Plotters Depth Sounder / Sonar ECDIS GPS Gyrocompass Integrated Bridge (IBS) Magnetic Compass Radar Systems & Marine Radar Service Satellite Compass Situation Awareness Speed LOGs Marine Steering Systems End of Life - Navigation Safety & Security AIS Marine Anti Piracy Systems BNWAS EPIRBs Marine Fire Detection and Monitoring GMDSS LRIT NAVTEX Radios - Handheld SART Shipboard and Marine CCTV Security Camera Solutions Situation Awareness SSAS Voyage Data Recorder - VDR Vessel Monitoring Systems End of Life - Safety & Security Anti-Pollution Fuel Blending System Fuel Consumption Measurement Fuel Viscosity Control Fuel/Flow Measurement Propulsion Performance Management Oil Discharge Monitor Oily Water Monitors & Calibration Services Oily Water Separator & Spares Torque Measurement End of Life - Anti Pollution Fishing AIS AutoPilot Catch Management Chart Plotters Depth & Echosounders Entertainment EPIRBS GPS & Satellite Compass Monitors & MFDs Radar Radios – Handheld Radios – Shipboard SARTS Satellite Phones Satcom Accessories — Iridium — Inmarsat Satcom L-Band Satcom Network - Fishing Satcom VSAT Sonar Subsea (SeaFloor Mapping) Vessel Monitoring Systems Trawl Gear End of Life - Fishing Land-Mobile SatCom Satellite Phones SatCom KITS SatCom Accessories — Iridium — Inmarsat Rentals Push-to-Talk (PTT) Portable BGAN Vehicular BGAN Iridium Certus® Fixed and Mobile VSAT - ESA Flat Panel VSAT - Parabolic M2M Satcom Networking & Security Satellite Airtime Partners Firmware Downloads End of Life - Land Mobile SatCom Cart Also of Interest Gyrocompass: The Key to Reliable Marine Navigation Anschütz Standard 30MF Gyro Compass YDK (Yokogawa) PT900 Autopilot Brands We Represent View All Search Search Quick Links About Mackay Careers Privacy Policy Terms of Use Site Map News Sales & Service Locations Contact Us myMackayOnline Marine Electronics Satellite Solutions Marine Services Service Request Form General Terms & Conditions Quick Links About Mackay Careers Privacy Policy Terms of Use Site Map News Sales & Service Locations Quick Links Contact Us myMackayOnline Marine Electronics Satellite Solutions Marine Services Service Request Form General Terms & Conditions Contact Us Mackay Communications 3691 Trust Drive Raleigh, NC 27616 USA +1 919-850-3000 © 2026 Mackay Communications, Inc., All Rights Reserved. + No products in the cart.
