14、ndards 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 established has the right to be represented on that committee. International or
15、ganizations, 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 standardization. International Standards are drafted in accordance with the rules give
16、n 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 voting. Publication as an International Standard requires approval by at least 7
17、5 % 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 such patent rights. International Standard ISO 22643 was prepared by the Consult
18、ative Committee for Space Data Systems (CCSDS) (as CCSDS 647.3-B-1, January 2002) and was adopted (without modifications except those stated in Clause 2 of this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information trans

30、ommittee for Space Data Systems (CCSDS) is an organization officially established by the management of member space Agencies. The Committee meets periodically to address data systems problems that are common to all participants, and to formulate sound technical solutions to these problems. Inasmuch
31、as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommendations and are not considered binding on any Agency. This Recommendation is issued by, and represents the consensus of, the CCSDS Plenary body. Agency endorsement of this Recommendation is ent
32、irely voluntary. Endorsement, however, indicates the following understandings: o Whenever an Agency establishes a CCSDS-related standard, this standard will be in accord with the relevant Recommendation. Establishing such a standard does not preclude other provisions which an Agency may develop. o W
33、henever an Agency establishes a CCSDS-related standard, the Agency will provide other CCSDS member Agencies with the following information: - The standard itself. - The anticipated date of initial operational capability. - The anticipated duration of operational service. o Specific service arrangeme
34、nts shall be made via memoranda of agreement. Neither this Recommendation nor any ensuing standard is a substitute for a memorandum of agreement. No later than five years from its date of issuance, this Recommendation will be reviewed by the CCSDS to determine whether it should: (1) remain in effect
35、 without change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or, (3) be retired or canceled. In those instances when a new version of a Recommendation is issued, existing CCSDS- related Agency standards and implementations are not negated or deemed
36、to be non-CCSDS compatible. It is the responsibility of each Agency to determine when such standards or implementations are to be modified. Each Agency is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommendation. BSISO
