Product Features

Yokogawa CMZ900D Gyrocompass

Features a highly reliable dual system configuration.

Features

  • The system configuration can easily be adapted to each vessel's specifications.
  • IEC 61162-2 high-speed code is available for the heading and rate of turn (ROT) outputs.
  • A unique anti-vibration system enhanced by the velocity damping effect of high viscous oil, provides superior damping of vibration and decoupling of shock at sea.
  • A small and lightweight container enhances the follow up speed. The gyrocompass changes smoothly and does not lag when a small vessel rapidly changes course.
  • A space-saving design: the master compass and the control box can be installed on the autopilot stand.
  • Automatic speed error correction is possible if both the ship's speed signal from the speed log and the latitude signal from a GPS or some other positioning device is available. Further, the latitude can be estimated from the ship's speed and the gyrocompass reading if the positioning device signal is absent.
  • An external heading signal from an instrument such as a magnetic compass or a GPS compass can be passed to repeater compasses and other ship equipment for back-up purposes.
  • Mechanical switchover as well as switchover by software control, is available to select which master compass can be used for the purpose of reliability on the switch action.
  • As a standard function, a built-in monitor detects deviations between the master compass and external sensor heading readings.
  • The restart time can be preset from 1 to 99 hours.
