The Standard 22 gyro compass was designed as a modular system to meet customer requirements. The system consists of up to three gyro compasses and can include an operator unit and a distribution unit. Another gyro, a magnetic compass, a satellite compass, and/or an external rate-of-turn gyro can be integrated as additional sensors. A wide range of accessories is available. Compliance to bridge alert management (BAM) standards The integrated heading monitor compares the heading infor- mation from up to four different compasses. An alert is given if a user-defined threshold is exceeded. In case of a gyro compass system alert, the system switches automatically to another compass as required for several class notations and defined by the user. Standard 22 is compliant to bridge alert management standards. Alerts are prioritized and presented in a consistent manner on the operator unit. Standard 22 allows also to transfer the alerts to a central alert management (CAM) display for a central alert presentation on the bridge. Alerts can be acknowledged from both, the operator unit and the CAM display. Independent transmitting magnetic compass (TMC) path The independent TMC path ensures that a failure in the gyro compass 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 on board of the vessel, resulting in cost savings for the ship yard and the ship owner. Speed / latitude error correction For the standard automatic speed / latitude error correction, speed and latitude data are provided by sensors or entered manually via the operator unit. The individual speed error correction function ensures that a failure in a log or GPS receiver only affects the heading of one gyro compass. Benefit: Subsequent systems such as dynamic positioning systems are able to detect a heading error caused by an incorrect latitude or speed information at an early stage. Integration of compasses The Standard 22 system allows integration of other compasses such as an existing gyro compass. By doing this a cost efficient interpretation of existing gyro compass or an upgrade from a gyro compass to a heading management system is possible. Standard 22 heading management system This systems allows to connect up to three gyro compasses and integrates a magnetic compass or GNSS compass. 12 serial outputs are available in addition to the outputs of Standard 22 for the connection of heading receivers, such as repeaters, autopilots, radars and others. Sensor selection is done 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 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 DNVGL NAUT-OSV/OC/AW, LR IBS or ABS NIBS. How can ship owners with older ships benefit from the various advantages the Standard 22 offers? Raytheon Anschütz offers a variety of converters that allow ship owners very cost-efficient retrofit solutions. Old gyro compasses transmit the heading information as analog synchro or step signals. Our new converters convert the serial/ digital heading information from new compasses into analog signals to allow the existing equipment to be kept aboard. The demand of Standard 22 gyro compass has steadily increased over the past years. Nevertheless, thanks to an optimized manufacturing process Raytheon Anschütz can offer the best availability of gyro compasses ever, together with a worldwide faster delivery time. This makes Standard 22 perfectly suited even for time-critical retrofits that cannot afford any delay.
