NEN-ISO 22090-2 specifies the construction, performance, and testing of a device employing only magnetic means as transmitting heading devices required by chapter V, SOLAS 1974 (as amended). A Transmitting Heading Device (THD) is an electronic device that provides information about the ship’s true heading. In addition to the general requirements contained in IMO Resolution A.694(17) to which IEC 60945 is associated and the relevant standard for the sensing part used, the THD equipment shall comply with the following minimum requirements. Where the IMO performance standards which apply to the sensing part do not specify a geographical operating area the THD shall operate a) at a minimum rate of turn 20 °/s and b) from 70° latitude south to 70° latitude north as a minimum. The THDs complying with the requirements contained in this part of ISO 22090 can be used for heading information as contained in chapter V of the SOLAS Convention. In addition such THDs are intended to meet the dynamic requirements contained in the HSC Code, chapterA standard magnetic compass with a pickup sensor could be applied as a sensing part of this standard of geomagnetic principle. However the IMO performance resolution MSC.116(73) requires that the THD is intended to be met for the dynamic requirements of the HSC code. Nevertheless, when the THD would be only used other than the HSC, the limit of rate of turn may be 6 °/s instead of 20 °/s. 13 for the carriage of a suitable device providing heading information.
