11、al 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 which a technical committee has been e

12、stablished 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 matters of electrotechnical standard

13、ization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for vo

14、ting. Publication as an International Standard 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all su

16、avigation 1 Scope This International Standard contains terms, abbreviations and graphical symbols, which are to be used in maritime navigation on board ships. The application of abbreviations is useful, but they should not be used in mathematical formulae. Symbols for use in mathematical formulae ar

Navigation is the process of position finding as well as planning, recording and controlling the movement of a craft or vehicle from one place to another. 2 Normative references The following referenced documents are indispensable for the application of this document.
