11、ld note that there is some disagreement between the definitions of identical terms in the three parts of this standard. The same applies to some notes and is due to the fact that the original English versions had not been drafted in a uniform manner. The DIN Standards corresponding to the Internatio
12、nal Standards referred to in Clause 2 of this standard are as follows: IEC 60945 DIN EN 60945 and Corrigendum 1 to DIN EN 60945 IEC 61162-1 DIN EN 61162-1 and Corrigendum 1 to DIN EN 61162-1 IEC 61162-2 DIN EN 61162-2 IEC 61924-2 DIN EN 61924-2 and Corrigendum 1 to DIN EN 61924-2 ISO 25862 DIN ISO 2
13、5862 Amendments This standard differs from DIN ISO 22090-1:2013-01 as follows: a) the requirements for heading information given in 4.6 have been amended, details regarding interface are now given in 4.9; b) Subclause 4.8 has been provided with a new heading “Alert signal”, the text has been amended
14、 in accordance with the new IMO Resolutions: provision of an interface for alert communications to indicate malfunctions of the heading transmission system (THD) or a failure of the power supply has been specified, and the data to be communicated according to the relevant IEC Publication in case of
15、alert have been laid down; c) a new Subclause 4.9 “Interface” with requirements regarding the interface for heading output and heading information to be communicated according to the relevant IEC Publication, and with the new updating rate (now once per 20 ms) has been included; d) a new Subclause 6
16、.12 with test requirements for the interface facilities specified in 4.8 and 4.9 has been included; e) in Annex A, the correlation of clauses and subclauses in ISO 22090-1 with those in IMO Resolution MSC.116 (73) has been corrected.

22、eThis part of ISO 22090 specifies the construction, performance, and testing of gyro-compasses as transmitting heading device required by chapter V, SOLAS 1974 (as amended).A Transmitting heading device (THD) is an electronic device that provides information about the ships true heading.In addition
23、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 that apply to the sensing part do not spe
24、cify a geographical operating area that the THD shall operatea) at maximum rate of turn 20 /s andb) from 70 latitude south to 70 latitude north as 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
25、 SOLAS Convention.However, ships within a speed range of 30 kn to 70 kn should comply with the requirements of IMO Resolution A.821(19).In addition, such THD should meet the dynamic requirements contained in the HSC Code, chapter 13 for the carriage of a suitable device providing heading information
26、.NOTE 1 Several technologies can be used to detect and transmit heading information. It is illogical to standardize the detection of the heading separately from the transmission of the heading. Therefore, separate parts of this part of ISO 22090 refer to different technologies. The requirements of t
27、his part of ISO 22090 only apply to gyroscopic technology. Other technologies are covered in other parts of ISO 22090.NOTE 2 All requirements that are extracted from the recommendations of IMO Resolution MSC. 116(73) on performance standards for transmitting heading devices are printed in italics.2
