9、ide, 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 established has the right to be represented on t
10、hat 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 standardization. Draft International Standards adopted
11、by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote.

20、atement of intent The Consultative Committee 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 sol
21、utions to these problems. Inasmuch 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 endors
22、ement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: 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
23、 which an Agency may develop. Whenever 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. Spe
24、cific service arrangements 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 shoul
25、d: 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 of a Recommendation is issued, existing CCSDS-related Agency standards and implementations are not
26、 negated or deemed 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 and implementations towards the later version of the Recommendati
27、on. CCSDS632.0-B-1 ii November1994BSZ10:1998 6 BSI 08-1999 Foreword This Recommendation extends the standardization of the Standard Formatted Data Unit (SFDU) concept in support of the digital transfer of space-related information. This Recommendation specifies standards for expressing selected data
28、 description attributes and for their packaging with the data description. The resulting packages, called Control Authority Data Structures (CADS), are used to submit data descriptions to Control Authority Offices for registration and revision and to disseminate data descriptions from Control Author
29、ity Offices. Other aspects of the SFDU concept are described in the documents identified in the References section. Through the process of normal evolution, it is expected that expansion, deletion, or modification to this document may occur. This Recommendation is therefore subject to CCSDS document
30、 management and change control procedures which are defined in reference 1.

36、 standard data structures to permit the writing and packaging of data descriptions; e) a standard set of media and protocols for communication within the organization and between users and the organization. Points a through c above are defined in the Control Authority Procedures Recommendation (refe
37、rence 2); the purpose of this document is to define point d to the extent needed to support registration and revision of data descriptions with Control Authority Offices and to support dissemination of data descriptions from Control Authority Offices. 1.2 Applicability This Recommendation applies to
38、 all Member Agency Control Authority Offices (MACAOs) and to all users of MACAO data description registration, revision, and dissemination services. The Recommendation does not preclude individual MACAOs from using locally developed formats where appropriate. 1.3 Recommended approach to reading the
39、document A proper understanding of this document requires familiarity with the SFDU concept; the rationale underlying the various product-building and packaging techniques, including the Parameter Value Language (PVL) used to construct statements; and the specific terminology used in this document.
40、If the reader does not have this familiarity, it is recommended that the documents identified in the References list(1.4) be read prior to reading this Recommendation. This document is structured as follows: section2 provides the context for the Control Authority Data Structures (CADS); section3 def
41、ines the CADS packages and specifies a data structure whose ADID=CCSD0007; section4 provides guidance on what changes can be made in CADS formatting options without compromising the information content; Annex Apresents the acronyms and abbreviations used in this document; Annex Bpresents the glossar
42、y of terms used in this document. 1.4 References The following documents contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All documents are subject to revision, and users of this Rec
43、ommendation are encouraged to investigate the possibility of applying the most recent editions of the documents indicated below.
