The ANSZ Gyro Comp Standard 20 Service Manual is a technical guide for installing, calibrating, troubleshooting, and maintaining a marine gyrocompass. It is not consumer entertainment — it’s professional-grade material for ships, yachts, and offshore vessels.

Contents include:

The Anschütz Standard 20 gyro compass is a widely used marine navigation instrument offering reliable true-heading information for ships. The service manual is essential for installation, routine maintenance, troubleshooting, calibration, and repair. This article summarizes key sections and practical maintenance guidance to help ship engineers and technicians keep the unit operating accurately and safely.

Do not attempt internal repairs using an internet-sourced manual.
→ Hire a certified Anschütz service engineer.
→ If you are a training technician, get the manual directly from Raytheon Anschütz after proving your credentials.

If you need only basic operator maintenance (cleaning, bulb replacement, battery change for backup), refer to the Operator’s Manual, not the service manual. anschutz gyro compass standard 20 service manual

The Anschütz Standard 20 Gyro Compass Service Manual is the primary technical resource for maintaining, installing, and repairing the Standard 20 system. This system is known for its absolute digital position pick-off and microprocessor-controlled heading correction. Core System Components

The manual details several critical hardware elements that require specific service attention: Gyrosphere: The sensitive core that measures orientation.

Distributor/Control Unit: Distributes the 24V supply and processes data from external inputs like GPS and Log.

Operator Unit: Provides digital displays of heading, error logs, and alarm statuses.

Supporting Fluids: A mixture of distilled water and specific supporting liquid essential for the gyrosphere’s buoyancy and cooling. Key Service & Maintenance Tasks The Raytheon Anschütz Gyro Compass Standard 20 service

Professional maintenance follows a structured set of intervals and procedures:

Initial Setup: Involves installing the gyrosphere into the outer sphere, filling it with distilled water/supporting liquid, and establishing plug-and-socket connections.

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

Regular Intervals: Major overhauls typically occur every 3 years, though components like the gyrosphere are rated for approximately 40,000 hours (over 4.5 years).

Fluid Maintenance: Checking and replacing supporting liquids and inspecting the pump unit to ensure proper fluid circulation.

Before diving into the manual itself, it’s important to understand why the Standard 20 remains a relevant system.

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.

Even with newer fiber-optic gyros (FOGs) on the market, thousands of vessels still rely on the Standard 20 because of its robustness, proven accuracy (within 0.5° of true north), and relative insensitivity to rapid changes in latitude and vessel motion.

The service manual is the key to preserving this legacy equipment.
