Anschütz has officially phased out the Standard 20 in favor of the Standard 30, 50, and the latest Gyro Compass 10 (GC 10) and GC 82. However, support is not dead:
If you are operating a Standard 20, you are essentially preserving a classic. The manual is your survival guide.
Modern technicians often prefer a digital PDF for searchability (Ctrl+F to find “bearing clearance”), but the paper manual has distinct advantages aboard ship:
Ideal solution: Keep a laminated paper copy in the gyro compartment and a PDF on the ship’s office computer and one tablet.
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:
| Symptom | Probable Cause | Service Manual Section | |--------|----------------|------------------------| | Heading oscillates ±several degrees | Latitude damping setting wrong | 5.2.3 – Set damping factor | | Repeater lag | Phase shift in resolver signals | 6.4 – Adjust follow-up system | | Error varies with ship’s heading | Residual deviation (gyro in bearings) | 7.1 – Perform 24-hour test | | Alarm “Amplifier” | Power supply board failure | 8.9 – Replace PCB, align gains |
The service manual provides a troubleshooting guide to help technicians identify and rectify problems. This includes:
Owning a service manual is only half the battle. Effective use follows a structured workflow:

Which would you like?
Finding a "proper article" for a specific technical manual like the Anschütz Gyro Compass Standard 20 typically involves locating the manufacturer's documentation or a verified marine technical guide.
While a full service manual is usually a proprietary PDF restricted to certified technicians, you can find the essential technical details and operational guides through the following resources: 1. Essential Technical & Service Overviews
The Standard 20 is known for its high-precision and "north-seeking" capabilities. A "proper article" or guide for servicing this unit generally covers:
Calibration & Alignment: Ensuring the compass is aligned according to manufacturer specs.
Error Management: Understanding speed and latitude errors, which occur due to the ship's motion and the Earth's rotation.
Performance Standards: According to IMO standards, the error should not exceed ±1∘plus or minus 1 raised to the composed with power 2. Reliable Documentation Sources
If you are looking for the actual manual or a deep-dive technical article, these platforms are the industry standards: Anschütz has officially phased out the Standard 20
Raytheon Anschütz (Manufacturer): The most reliable source for the Standard 20 Service Manual and technical bulletins.
Technical Repositories: Sites like Scribd often host PDF versions of service manuals and detailed troubleshooting guides uploaded by marine engineers.
Marine Maintenance Blogs: For practical "how-to" advice on lubrication and power supply integrity, the Trionics Maintenance Guide provides a modern perspective on keeping these systems operational. 3. Key Maintenance Checklist
If you are performing a service, ensure you address these three pillars:
Lubrication: Prevent friction-related issues in the moving parts of the fast-spinning disc.
Power Supply: Verify all connections to avoid malfunctions during critical navigation.
Correction Tables: Use speed correction formulas to adjust for the Coriolis effect.
The official Raytheon Anschütz Gyro Compass Standard 20 Service Manual
is a comprehensive 92-page technical document covering installation, maintenance, and shipboard repair. It is primarily designed for trained personnel and includes critical data for the Standard 20, Compact, and Plus variants. Key Service Manual Sections If you are operating a Standard 20, you
Installation & Commissioning: Detailed instructions on physical mounting, filling the supporting liquid and distilled water, and performing initial startup tests.
Maintenance Procedures: Standard care routines such as checking liquid levels, cleaning components, and scheduled part replacements.
Shipboard Repair: Guidance on troubleshooting common faults, exchanging major parts like the gyrosphere (Type 111-006), and reading out diagnostic data.
Technical Specifications: Electrical data, power consumption (up to 140W during heating), and environmental tolerances (-10°C to +55°C).
Spare Parts Catalog: A full list of assembly types, such as the Gyro Compass Casing (Type 110-222) and specific supporting liquids (Type 148-162). Critical Safety & Operational Notes
Run-down Time: After switching off, the gyro rotors require approximately 15 to 30 minutes to come to a complete standstill. Opening the compass before this period can permanently damage the gyrosphere.
Settling Time: The system requires roughly 3 to 5 hours after startup to reach full accuracy (± 0.1°) before it can be used for navigation.
Heating Phase: During initial operation, the digital display will show the supporting liquid temperature (e.g., "h28.8" for 28.8°C) until it reaches the operating threshold of 45°C. Where to Access Documentation
