Raytheon Anschütz STD22 Gyrocompass is a marine gyrocompass system from the Standard 22 series by Anschütz, a renowned brand in navigation equipment and marine bridge systems. The product is developed to provide accurate, stable, and continuous heading data for onboard navigation equipment.

Unlike traditional magnetic compasses, a gyrocompass does not directly rely on the Earth's magnetic field, thus minimizing interference from the ship's steel structure, magnetic disturbances, or surrounding electronic devices. It is a crucial component in the navigation system, typically interfaced with radar, ECDIS, autopilot, AIS, VDR, and other navigation equipment.

According to system documentation, the Standard 22 is designed for high accuracy and reliability in harsh marine operating conditions, while supporting flexible integration configurations tailored to the specific requirements of each vessel.

High Accuracy, Stable Operation in Marine Environments

A key feature of the Anschütz Standard 22 Gyro Compass is its ability to deliver stable and precise heading information over extended periods. The system is designed for demanding operational environments such as commercial vessels, cargo ships, service vessels, high-speed craft, and professional maritime systems.

The Standard 22 gyrocompass utilizes patented data transmission technology, replacing traditional slip rings, which enhances operational safety and reduces mechanical wear. This contributes to more durable system performance and helps lower maintenance costs throughout the equipment's lifecycle.

Integration of multiple heading sensors

A significant advantage of the Raytheon Anschütz Standard 22 is its ability to integrate various heading sensors and related devices. The system can connect to data sources such as:

• Gyro Compass.
• Transmitting Magnetic Compass (TMC).
• GPS Compass.
• HRG – Hemispherical Resonator Gyro.
• FOG – Fiber Optic Gyro.
• Rate-of-Turn Gyro.

This integration capability allows the system to manage the vessel's heading more effectively, especially on ships requiring stable heading data for multiple devices like ARPA radar, ECDIS, autopilot, and central navigation systems.

Speed and Latitude Error Correction

STD22 supports correction for speed and latitude errors, including both manual and automatic correction modes. This is a crucial feature for gyro compasses, as heading error can be affected by the vessel's geographical location and speed.

The technical documentation for the Standard 22 indicates that the Speed Error Correction function can operate when the system is connected to GPS or a Pulse Log, providing the necessary data to correct heading errors.

The Quick Settling function helps to reduce stabilization time.

Quick Settling is a function that helps the gyrocompass settle in a shorter initial stabilization time after startup. This feature is particularly useful in situations where the vessel needs to bring its navigation system to a ready state faster.

According to the Standard 22 brochure, the Quick Settling option can reduce stabilization time to approximately 1 hour, saving valuable preparation time before the vessel departs port or after the system has been powered up again.

Supports redundant systems, ensuring no heading data loss

For vessels requiring high safety, the Standard 22 can be configured as a redundant gyrocompass system. A redundant configuration can include two gyrocompasses, two Distribution Units, two Operator Units, and one Change-over Unit.

This design helps maintain heading data for connected equipment even if a single component fails. According to product documentation, the redundant system is designed such that no single fault will result in the loss of heading information supplied to relevant maritime equipment.

Accurate ROT output to IMO standards

STD22 is capable of providing theRate of Turn – ROTsignal, which is the vessel's turning speed. This is critical data for navigation systems, autopilots, radars, and voyage monitoring equipment.

The product is introduced as having a high-accuracy ROT output as required by the IMO, and is approved for use on standard and high-speed vessels. Some technical sources also note that the Standard 22 is IMO approved for standard craft, high-speed craft, and rate-of-turn gyro functions.
