27、O 17808:2014 ISO 17808:2014(E)BS ISO 17808:2014CCSDS RECOMMENDED PRACTICE CONCERNING TM CHANNEL CODING PROFILES 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 t

28、o 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 voluntary, the results of Committee actions are termed Recommendations and are not in themselves considered binding

29、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 elements of their space mission support infrastructure shall operate and interoperate with others; and Recommende

30、d 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 Practice is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommended P

31、ractice 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 issuance, this Recommended Practice will be reviewed by the CCSDS to determine whether it should: (1) remain

32、 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 Recommended Practice is issued, existing CCSDS-related member Practices and implementations are not nega

33、ted 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 encouraged to direct planning for its new Practices and implementations towards the later version of the Recomme

34、nded Practice.

Communication profiles for space-to-Earth links that are currently not supported by CCSDS, e.g., via data relay satellites, are not addressed in this document. 1.3 RATIONALE Over the years, CCSDS has standardized a set of schemes for forward error correction coding

46、based on state-of-the-art techniques. Indeed, since the needs of missions can be very different, a single type of code would not satisfy all the needs, and possible selections should be offered to the users. CCSDS 131.4-M-1 Page 1-1 July 2011 BS ISO 17808:2014 ISO 17808:2014(E)BS ISO 17808:2014CCSDS

47、 RECOMMENDED PRACTICE CONCERNING TM CHANNEL CODING PROFILES For instance, deep space missions generally operate at low data rates and have, in general, rather mild bandwidth constraints; on the other hand, link performances are crucial and high coding gain is required. Conversely, near-Earth mission

48、s, be they for space research, for space operations, or for Earth exploration, may operate at high or very high data rates on their telemetry link and require, in general, a compromise between coding gain and bandwidth expansion. Punctured convolutional codes were developed specifically for these pr

49、ofiles. Recently introduced LDPC codes appear as a possible alternative with better performances. Some mission profiles involve highly dynamic links. One of the cases is represented by Earth exploration satellites operating on low Earth orbits. The increasing amount of data to dump to Earth during the short contacts with ground stations requires ever increasing data throughput; techniques based on Variable Coding and Modulation (VCM) are a means to account for the dynami
