Product Introduction
The Raytheon Anschütz Standard 22 (STD 22) Gyro Compass is one of the world's most trusted marine heading reference systems. Designed for continuous operation in demanding maritime environments, the STD 22 provides highly accurate true heading information to critical navigation systems onboard ships.
Unlike magnetic compasses, gyro compasses determine True North rather than Magnetic North, making them indispensable for modern navigation.
The Standard 22 has been installed on thousands of vessels worldwide, including:
- Container Ships
- Oil Tankers
- LNG Carriers
- Bulk Carriers
- Offshore Support Vessels
- Passenger Ships
- Naval Vessels

What Is a Gyro Compass?
A gyro compass is a navigation instrument that uses the principles of gyroscopic motion and the Earth's rotation to find and maintain True North.
Unlike a magnetic compass, a gyro compass:
- Is not affected by magnetic interference
- Provides true heading information
- Offers higher accuracy
- Supports modern navigation systems
- Integrates with bridge equipment
Today, gyro compasses are considered essential navigation equipment on commercial vessels.
Raytheon Anschütz Standard 22 System
Working Principle of the Standard 22
The STD 22 operates using:
Gyroscopic Stability
A rapidly spinning gyroscope maintains directional stability.
Earth's Rotation Detection
The system senses the Earth's rotational movement and aligns itself with True North.
Electronic Heading Processing
Internal processors continuously calculate heading corrections and maintain accuracy.
Continuous Heading Distribution
The heading data is distributed to:
- Radar
- ECDIS
- AIS
- Autopilot
- Voyage Data Recorder (VDR)
- Bridge Repeaters
Internal Gyro Components

Gyro Compass Repeaters & Navigation Integration
Why Ships Still Use Gyro Compasses
Although GPS provides accurate position information, ships still require gyro compasses because:
- GPS Does Not Provide Continuous True Heading
- Radar Requires Stable Heading Input
- Autopilots Need Accurate Heading Reference
- ECDIS Relies on Heading Data
- AIS Transmits Vessel Heading
- Collision Avoidance Depends on Accurate Navigation Data
For these reasons, gyro compasses remain essential equipment on modern vessels.
