The work of preparing International Standards is
12、 normally carried out through ISO technical committees. Each member body interested in a subject for which 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
13、 in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particula
14、r the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this
15、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.is
16、o.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the W
17、TO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation and ship operations.This second edition cancels and replaces the first
18、 edition (ISO 22090-3:2004), of which has been technically revised. It also replaces ISO 22090-3:2004/Cor1:2005.ISO 22090 consists of the following parts, under the general title Ships and marine technology Transmitting heading devices (THDs): Part 1: Gyro-compasses Part 2: Geomagnetic principles Pa

20、 of transmitting heading device using GNSS principle as required by chapter V, SOLAS 1974 (as amended).A transmitting heading device (THD) is an electric device that provides information about the ships true heading.In addition to the general requirements contained in IMO Resolution A.694(17) to whi
21、ch 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 specify a geographical operating area, the THD shall operatea) at a maximum
22、 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 SOLAS Convention.In addition, such THDs should meet the dynamic requiremen
23、ts contained in the HSC Code, chapter 13 for the carriage of a suitable device providing heading information.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
24、. Therefore, separate parts of this part of ISO 22090 refer to different technologies. The requirements of this part of ISO 22090 only apply to the principle of the GNSS. Other technologies are covered in other parts of ISO 22090.NOTE 2 All requirements that are extracted from the recommendation of
25、IMO Resolution MSC. 116(73) on performance standards for transmitting heading devices are printed in italics.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

33、agement3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1headingships heading to be input to the THD functionNote 1 to entry: It is defined by the direction of the vertical projection of the fore-and-aft line of the ship onto the horizontal plane.
34、 When measured relative to the true north, magnetic north, or compass north, it is respectively defined as true heading, magnetic heading, or compass heading, and is usually expressed in degrees as a three-figure group, starting from north, in a clockwise direction around the compass card.3.2sensing
