9、 ersedevr iiiForeword 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
10、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 in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) o
11、n all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees
12、are circulated to the member bodies for voting. 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 International Standard may be the subject of patent rights. ISO sha
13、ll not be held responsible for identifying any or all such patent rights. International Standard ISO 14961 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as CCSDS 641.0-B.2, June 2000) and was adopted (without modifications except those stated in clause 2 of this Internat
14、ional Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information transfer systems. This second edition cancels and replaces the first edition (ISO 14961:1997), which has been technically revised. BSISO14961:2002iiiINTENRATIONAL TSANDADR IS
