This article is a technical summary for educational purposes. For actual maintenance, refer to the official Anschütz Standard 20 Service Manual and follow all safety instructions. Improper service can lead to total compass failure and hazardous navigation errors.
Anschütz Gyro Compass Standard 20 Service Manual is a technical document provided by Raytheon Marine GmbH (Anschütz) that serves as the definitive guide for the installation, maintenance, and shipboard repair of the Standard 20 series. This system, used extensively for maritime navigation, utilizes an absolute digital pick-off system to provide a true north heading independent of the Earth’s magnetic field. Core Technical Overview
The Standard 20 is designed as a modular system, typically consisting of the gyro compass unit, a control unit, and an operator unit. Its operation relies on a complex interplay of mechanical and electrical components: Gyrosphere
: The central sensor responsible for determining orientation. Supporting Liquid
: A specialized fluid (distilled water and liquid mix) used to float the gyrosphere and regulate its temperature. Absolute Digital Pick-off
: A 16-bit optical system that provides high-resolution heading data (0.3 arc min). Automatic Correction anschutz gyro compass standard 20 service manual
: The system digitally corrects for speed and latitude errors, often interfacing with GPS and logs for redundant operation. Essential Service Procedures
The service manual details several critical maintenance and operational tasks required for system reliability: Initial Commissioning
: This includes filling the system with supporting liquids, installing internal components, and performing initial leveling tests and adjustments. Heating and Settling Phases
: Upon switching on 24V DC power, the system enters a heating phase until the supporting liquid reaches approximately 45°C. : A stabilization period of roughly 3 to 5 hours
is required before the heading is considered valid and accurate. Periodic Maintenance Comprehensive Service Guide for the Anschütz Standard 20
: Technicians must regularly check liquid levels, inspect slip rings, and replace filters or heating cartridges as needed. Gyrospheres generally require replacement or overhaul every 1 to 5 years. Troubleshooting and Error Codes
The manual provides a diagnostic framework through digital error codes (E1 to E9) displayed on the operator unit. Key alerts include: Gyro Compass Equipment STD 20 Plus GG - Anschuetz
Anschütz Gyro Compass Standard 20 is a critical marine navigation instrument that determines true north independently of the earth's magnetic field. Proper service and maintenance, guided by the Anschütz Standard 20 Service Manual
, are essential for ensuring accurate heading signals and long-term reliability. Core Components of the Standard 20 The system is comprised of several high-precision modules: Gyro Compass Casing : Includes the outer sphere (Type 110-222). Gyrosphere
: The sensitive element (Type 111-006) that provides the north-seeking capability. Supporting Liquid Always log run-time hours
: A specialized fluid (Type 148-162) and distilled water (Type 148-398) used to suspend the gyrosphere. Electronic Units
: Control and operator units that process heading signals and perform speed-error corrections. Maintenance Intervals and Procedures
Regular servicing prevents equipment failure and ensures compliance with maritime regulations. Gyro Compass Equipment STD 20 Plus GG - Anschuetz
