Yokogawa, primarily known for industrial automation, has a specialized division for marine navigation systems. The Yokogawa Gyro Compass (YG Series) is a known for its high static accuracy, rapid settling time, and low maintenance requirements. Unlike GPS-based heading sensors, it is immune to satellite jamming and provides true north referencing independent of external signals. The models YG-300 and YG-500 are the most prominent in the mid-to-large vessel segment.
Yokogawa, founded in 1915, was initially a powerhouse in industrial measurement and control. When they turned their attention to maritime navigation, they didn't just copy existing designs; they optimized them for the harsh realities of the sea. yokogawa gyro compass

The system includes gravity-sensitive components that create a torque, forcing the gyroscope to seek the meridian. This eliminates the "magnetic variation" and "deviation" errors common in traditional compasses. The CMZ900 Series: Current Industry Standard The models YG-300 and YG-500 are the most
The (now manufactured under the YDK Technologies brand) is a cornerstone of modern maritime navigation. Unlike traditional magnetic compasses, these systems utilize the principles of gyroscopic motion and the Earth's rotation to point toward True North , providing critical heading data for everything from cargo ships to high-speed naval vessels. Core Technology and Working Principle
Furthermore, Yokogawa has integrated their gyro technology into the modern "Integrated Bridge System." The gyro doesn't just tell the captain where the ship is pointing; it feeds that data into the autopilot, the radar overlay, and the Electronic Chart Display and Information System (ECDIS). It creates a seamless digital mesh of navigation data.
