21、sedevre Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for w
22、hich a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
23、 matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International St
24、andard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Internat
25、ional Standard ISO 11674 was prepared jointly by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation and IEC/TC 80, Maritime navigation and radiocommunication equipment and systems.

It applies to the heading c
27、ontrol systems which enable a ship to keep a preset heading with minimum operation of the ships steering gear, within limits related to the ships manoeuvrability in conjunction with their sources of heading information. The heading control system may work together with a track control system adjusti
28、ng its heading for drift. A turn rate control or a turning-radius control for performing turns may be provided. NOTEAll the text in this International Standard identical to that in IMO Resolutions Resolution A.342(IX) as amended by resolution MSC.64(67), annex 3 and Resolution A.694(17) are printed
29、in italics. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However parties
30、 to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain
