Anschutz Gyro Compass Standard 20 Service Manual Jun 2026

Routine verification of phase voltage, phase current, and the height/balance of the sensitive element.

The system is sensitive to electrostatic discharge (ESD). 7. Conclusion

Verify all connections to avoid malfunctions during critical navigation.

Contaminated supporting fluid, low fluid levels, or aging gyro rotors.

A key aspect detailed in the maintenance section is the replacement of the gyro sphere. The manual provides a step-by-step procedure for this delicate operation, ensuring that the sensitive components are not damaged during handling. It specifies the tools required, the torque settings for seals, and the procedures for purging air from the system. Adherence to these protocols ensures the longevity of the equipment and prevents catastrophic failures at sea. Furthermore, the manual lists the specific lubricants and consumables approved for use, preventing the use of incompatible substances that could degrade the compass’s performance.

Compare the baseline reference to the current master compass reading. Routine verification of phase voltage, phase current, and

Use a clean siphon or syringe to remove the old fluid from the outer container.

Measure the internal test points using a digital multimeter to confirm they match factory specifications.

: The system requires roughly 3 to 5 hours after startup to reach full accuracy (± 0.1°) before it can be used for navigation.

Introduced by Raytheon Anschütz (now part of Raytheon Marine GmbH), the Standard 20 series represented a leap forward in gyrocompass technology. Unlike magnetic compasses, a gyrocompass seeks true north, unaffected by the Earth’s magnetic field. The Standard 20 uses a electrically suspended gyrosphere (typically 20 cm in diameter) spinning at high revolutions—around 20,000 rpm—to achieve this.
