Standard 22 NX

Accuracy and reliability under all environmental conditions

Anschütz designed the Standard 22 NX gyrocompass for high accuracy, reliability and operational safety even under the harshest environmental conditions for all kind of ships. With interfaces for serial data, Ethernet and Bridge Alert Management (BAM), it offers an easy installation and integration. The Standard 22 NX is available as a standalone system or as part of an advanced heading management system.

Benefits

icon_gyro_compass_circle
The upmost in reliability

Standard 22 NX is extremely reliable thanks to its superior sensor technology, high manufacturing quality and a unique, resistant design that reduces environmental influence (i.e. shocks, vibrations). The high accuracy of heading information has been proven in more than 25,000 installations, including on ships operating in high latitudes.

Installation and maintenance made easy

Thanks to its multiple standardised interfaces, Standard 22 NX is quick and easy to install in the most varied system environments. It is set up using standard cabling (redundang CAN bus) with less wiring effort. Configuration, software updates and diagnosis are easily done via a webserver without the need for any proprietary tools. Standard 22 NX also comes with minimal wear due to inductive and optical transmission and no use of slip rings, and with a fail-safe pump.

Secure investment

Standard 22 NX offers an unsurpassed price-performance ratio over the entire lifetime and the best value for money in newbuild and retrofit projects. This results from a long lifespan of its gyrospheres, its long maintenance intervals and a long-term stability of its heading performance. 

Main
Features

  • High accuracy of 0.4° sec Lat. RMS
  • Inductive and optical data transmission, no slip rings that are subject to wear
  • Speed/latitude error correction
  • Connected via CAN bus, enabling cable lengths of up to 400m (in comparison to Ethernet connections that can only reach a maximum of 80m)
  • Webserver functionality for configuration, software updates and diagnosis, configuration possible in 2 minutes by upload of configuration file
  • Quick settling mode reduces settling time to 1 hour
  • Approved as gyrocompass, gyrocompass for high speed craft, and rate-of-turn indicator
Jamming & Spoofing
Modular system architecture

A modular product range enables different system configurations – from a single compass up to a multi-compass system consisting of magnetic compass, Standard 22 NX, Standard 30 MF and redundancy in distribution. The integration into such an advanced heading management system is realised through redundant CAN bus interfaces. Heading management systems offer further benefits, including added safety.

Heading management system
Transmitting Magnetic Compass (TMC) path

The independent TMC path ensures that a failure in the gyrocompass system does not affect the processing of the magnetic heading. With this function, various flag state authorities no longer require an optical bypass for the magnetic compass onboard the vessel, resulting in cost savings for the shipyard and the ship owner.

Automatic correction of magnetic heading variation

The system can correct the variation of the magnetic heading automatically when an RMC telegram is input from a GNSS receiver that contains the variation error. Benefit: automatic improvement of the magnetic heading accuracy and, thus, of the heading monitoring between gyrocompass heading and magnetic compass heading. 

Integrated heading monitor

The heading management system features an integrated heading monitor that compares the heading information from up to four different compasses. An alert is given if a user-defined threshold is exceeded. In case of an alert, the system switches automatically to another compass as required for several class notations and defined by the user.

Anschütz heading management systems combine Standard 22 NX and Standard 30 MF gyrocompasses in any combination and can also integrate third party compasses (up to three gyrocompasses, or two gyros and a GNSS THD, and a magnetic compass). Even existing gyrocompass installations can be easily expanded. Anschütz gyrocompasses are integrated via a standard CAN bus without the need for complex specialised integration electronics.

Standard 22 NX
heading management system

This system allows the connection to up to three gyrocompasses (or two gyrocompasses and one GNSS compass) and integrates a magnetic compass. In addition to the 4 serial outputs of Standard 22 NX, 12 outputs for the connection of heading receivers such as repeaters, autopilots, radars and others are available. Sensors are selected with the operator unit. The threshold for a heading difference between different compasses can be defined by the user and is continuously monitored. Thanks to the CAN bus, the wiring effort between the compass components is reduced to a minimum.

Standard 22 NX
heading management system with redundancy in distribution

This system provides a redundancy of the distribution system in addition to the redundancy of compasses. No single failure in this configuration causes a loss of heading information to the connected heading receivers. Such a system (with two gyros) is compliant to the demanding class notations such as DNV NAUT-OSV/OC/AW, LR IBS or ABS NIBS.

Standard 22 NX M
– gyrocompass solution for naval ships

Standard 22 NX M continues the series of Anschütz gyrocompasses for naval ships. With the same advantages as the commercial Standard 22 NX, it has proven its outstanding reliability and robustness in a long-term factory test and is also qualified acc. to MIL Standard and BV0430. Thanks to its various interfaces and formats for serial data communication, Ethernet communication and BAM, it is easy to install in newbuilds and refits.

Interfaces & standards

3x serial inputs for position, speed and BAM
4x serial outputs for heading, rate of turn and BAM
1x analogue output for rate of turn for 30°/min, 100°/min or 300°/min
2x Ethernet interfaces for bridge systems such as radar and ECDIS

  • Ethernet communication according to IEC 61162-450
  • Cyber security requirements according to IACS UR E27
  • BAM communication according to IEC62923-1 and -2

 

BAM: Alerts are prioritised and presented on the operator unit in a consistent manner. Standard 22 NX also allows to transfer the alerts to a central alert management display for a central presentation on the bridge. Alerts can be acknowledged bidirectionally.
