Anschutz Gyro Compass Standard 20 Service Manual [2021] Now
Verify that heading repeaters match the master compass heading exactly. Annual Service Checks
The Standard 20 M features digital pick-offs and electronic speed/latitude error correction, requiring precise, software-guided calibration as outlined in the service manual. 2. Key Sections in the Service Manual
If the fluid becomes cloudy or the sphere shows erratic behavior, a fluid change is necessary:
According to IMO standards , the error should not exceed ±1∘plus or minus 1 raised to the composed with power 2. Reliable Documentation Sources anschutz gyro compass standard 20 service manual
To maintain true north accuracy, the Standard 20 must compensate for speed, latitude, and course errors (known as the quadrant error or speed-error correction).
: The Standard 20 is noted for its "proven performance" and modular design, allowing it to be custom-fitted to various installation requirements. Safety Criticality
: Loss of communication between the operator unit and the CAN Bus system. Verify that heading repeaters match the master compass
Regular servicing is vital to preserve the performance of the system and comply with regulations. www.isik.com.tr Anschutz gyro compass standard 20 service manual
: The system digitally processes and corrects for speed and latitude-dependent errors (physically-conditioned speed error) and "oil-damping residual error" caused by the movement of damping oil during heading changes.

: Manufacturer guidelines for safe handling, operation, and maintenance of the system, including compliance with EC Directive 96/98/EC and the Declaration of Conformity.
One of the most valuable sections of the service manual is the list of spare parts, which uses a standardized seven-digit part number system to ensure you procure the correct, certified components directly from OEM or authorized sources. The service manual is also a gateway to a global support network. Raytheon Anschütz maintains more than 200 sales and service representatives worldwide, providing around-the-clock service to ensure vessel safety. For specialized repairs, especially those involving the gyrosphere, it is crucial to engage qualified service centers like those operated by Synchronics or SEANAV. These authorized centers have the technical expertise and specialized diagnostic equipment to perform complex repairs and final calibrations that are simply not possible to carry out on a vessel at sea.
After replacing internal components or undergoing major dry-dock repairs, you must re-align the compass.
| Task | Typical Interval | Why It's Important | | :--- | :--- | :--- | | Full System Cleaning & Inspection | Annual | Prevents system failures from contamination and identifies potential issues early. | | Calibration and Heading Alignment | Annual | Ensures the compass remains accurate and compliant. | | Sensitive Element (Gyrosphere) Replacement | Every 4 years | This is a core component with a finite lifespan. Timely replacement prevents sudden failure and inaccuracy. | | Replacement of Brushes and Other Wear Parts | 2–6 years, depending on part | Prevents mechanical failure due to wear. The manual specifies exact intervals for all moving parts. |
