8、 All rights reserved 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
9、 a subject 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 Commiss
10、ion (IEC) on all matters of electrotechnical 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
11、committees 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 document may be the subject of patent rights. ISO shall
12、not be held responsible for identifying any or all such patent rights. ISO 22641 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as CCSDS 131.0-B-2, August 2011) and was adopted (without modifications except those stated in Clause 2 of this International Standard) by Techn
13、ical 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 22641:2005), which has been technically revised. BS ISO 22641:2012BS ISO 22641:2012INTERNATIONAL STANDARD ISO 22641:

16、he users of this specification, b) data formats, and c) the procedures performed to generate and process the data formats. 1.3 This International Standard does not specify a) individual implementations or products, b) the methods or technologies required to perform the procedures, or c) the manageme

18、following pages), which is adopted as an International Standard: CCSDS 131.0-B-2, August 2011, TM synchronization and channel coding. For the purposes of international standardization, the modifications outlined below shall apply to the specific clauses and paragraphs of publication CCSDS 131.0-B-2.

26、SYNCHRONIZATION AND CHANNEL CODING CCSDS 131.0-B-2 Page ii August 2011 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of its members. The Committee meets periodically to address data systems problems that are
27、common to all participants, and to formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommended Standards and are not considered binding on any Agency. This Recommended Standard is issue
28、d by, and represents the consensus of, the CCSDS members. Endorsement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever a member establishes a CCSDS-related standard, this standard will be in accord with the relevant Recommended St
29、andard. Establishing such a standard does not preclude other provisions which a member may develop. o Whenever a member establishes a CCSDS-related standard, that member will provide other CCSDS members with the following information: - The standard itself. - The anticipated date of initial operatio
30、nal capability. - The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neither this Recommended Standard nor any ensuing standard is a substitute for a memorandum of agreement. No later than five years from its date of issuance, t
31、his Recommended Standard 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 of a Recomme
32、nded Standard is issued, existing CCSDS-related member standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such standards or implementations are to be modified. Each member is, however, strongly encouraged to d
33、irect planning for its new standards and implementations towards the later version of the Recommended Standard.

34、ment is a technical Recommended Standard for use in developing synchronization and channel coding systems and has been prepared by the Consultative Committee for Space Data Systems (CCSDS). The synchronization and channel coding concept described herein is intended for missions that are cross-suppor
35、ted between Agencies of the CCSDS. This Recommended Standard establishes a common framework and provides a common basis for the synchronization and channel coding schemes to be used by space missions with the TM or AOS Space Data Link Protocol (references 1 or 2) over space-to-ground and space-to-sp
36、ace communications links. This Recommended Standard was developed by consolidating the specifications regarding synchronization and channel coding in older CCSDS Recommended Standards (references E2 and E3). This Recommended Standard does not change the major technical contents defined in references
37、 E2 and E3, but the presentation of the specification has been changed so that: a) these schemes can be used to transfer any data over any space link in either direction; b) all CCSDS space link protocols are specified in a unified manner; c) the layered model matches the Open Systems Interconnectio
38、n (OSI) Basic Reference Model (reference 3). Together with the change in presentation, a few technical specifications in references E2 and E3 have been changed in order to define all Space Data Link Protocols in a unified way. Also, some technical terms in references E2 and E3 have been changed in o
39、rder to unify the terminology used in all the CCSDS Recommended Standards that define space link protocols and to define these schemes as general communications schemes. These changes are listed in annex H of this Recommended Standard. Through the process of normal evolution, it is expected that exp
40、ansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control procedures, which are defined in the Procedures Manual for the Consultative Committee for Space Data Systems. Current versions of CCSDS documen
41、ts are maintained at the CCSDS Web site: http:/www.ccsds.org/ Questions relating to the contents or status of this document should be addressed to the CCSDS Secretariat at the address indicated on page i.
