Yokogawa Denshikiki Co., Ltd.




This type is suitable for small vessels.



  • 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 can be installed on the autopilot stand.
  • The restart time can be preset from 1 to 99 hours.
