8、ord 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 which a techni
9、cal 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 matters of e
10、lectrotechnical standardization. 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
11、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 document may be the subject of patent rights. ISO shall not be held responsible for i
12、dentifying any or all such patent rights. ISO 20213 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as CCSDS 875.0-M-1, November 2012) and was adopted (without modifications except those stated in clause 2 of this International Standard) by Technical Committee ISO/TC 20, A

18、 an organization officially established by the management of its members. 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 as participation in the CCSDS is completely voluntar
19、y, the results of Committee actions are termed Recommendations and are not in themselves considered binding on any Agency. CCSDS Recommendations take two forms: Recommended Standards that are prescriptive and are the formal vehicles by which CCSDS Agencies create the standards that specify how eleme
20、nts of their space mission support infrastructure shall operate and interoperate with others; and Recommended Practices that are more descriptive in nature and are intended to provide general guidance about how to approach a particular problem associated with space mission support. This Recommended
21、Practice is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommended Practice is entirely voluntary and does not imply a commitment by any Agency or organization to implement its recommendations in a prescriptive sense. No later than five years from its date of
22、issuance, this Recommended Practice will be reviewed by the CCSDS to determine whether it should: (1) remain in effect 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 o
23、f a Recommended Practice is issued, existing CCSDS-related member Practices and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such Practices or implementations are to be modified. Each member is, however, strongly enco
24、uraged to direct planning for its new Practices and implementations towards the later version of the Recommended Practice.

25、document is a technical Recommended Practice for use in developing flight and ground systems for space missions and has been prepared by the Consultative Committee for Space Data Systems (CCSDS). The Message Transfer Service described herein is intended for missions that are cross-supported between
26、Agencies of the CCSDS, in the framework of the Spacecraft Onboard Interface Services (SOIS) CCSDS area. This Recommended Practice specifies services and service interfaces provided by the SOIS Message Transfer Service, which provides a standard service for mediating the transfer of discrete data, i.
27、e., messages, between onboard software users in a (potentially) distributed onboard system regardless of the particular type of data link or protocol being used for communication. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may o
28、ccur. This Recommended Practice is therefore subject to CCSDS document management and change control procedures, which are defined in the Organization and Processes for the Consultative Committee for Space Data Systems (CCSDS A02.1-Y-3). Current versions of CCSDS documents are maintained at the CCSD
