Space data and information transfer systems — Telemetry (TM) channel coding profiles

ISO 17808:2014 presents recommendations regarding the usage of coding schemes described in references [1]-[2] in the various mission profiles that are encountered in space research, space operations, and Earth exploration. Within this document, it is assumed that at the sending end the Synchronization and Channel Coding sublayer accepts at a constant rate transfer frames of fixed length from the Data Link protocol sublayer; performs the encoding and synchronization functions selected for the mission; and delivers a continuous and contiguous stream of channel symbols to the Physical layer. At the receiving end, the Synchronization and Channel Coding sublayer: accepts a continuous and contiguous stream of channel symbols from the Physical layer; performs the synchronization and decoding functions selected for the mission; delivers transfer frames to the Data Link protocol sublayer. Profiles for Earth-to-space and Proximity links are out of scope and are not addressed in this document. 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.

Foreword
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 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
Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described in the
ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO
documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any patent rights identified
during the development of the document will be in the Introduction and/or on the ISO list of patent declarations
received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not constitute an
endorsement.

Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and

INTERNATIONAL STANDARD ISO 17808:2014(E)

Space data and information transfer systems — Telemetry (TM)
channel coding profiles
1 Scope
This International Standard presents recommendations regarding the usage of coding schemes described in
references [1]-[2] in the various mission profiles that are encountered in space research, space operations,
and Earth exploration.
Within this document, it is assumed that at the sending end the Synchronization and Channel Coding sublayer
 accepts at a constant rate transfer frames of fixed length from the Data Link protocol sublayer;
 performs the encoding and synchronization functions selected for the mission; and
 delivers a continuous and contiguous stream of channel symbols to the Physical layer.
At the receiving end, the Synchronization and Channel Coding sublayer:
 accepts a continuous and contiguous stream of channel symbols from the Physical layer;
 performs the synchronization and decoding functions selected for the mission;
NOTE The decoding functions include validation of frames to determine their quality with respect to the possible
presence of undetected errors.
 delivers transfer frames to the Data Link protocol sublayer.
Profiles for Earth-to-space and Proximity links are out of scope and are not addressed in this document.
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.
2 Requirements
Requirements are the technical recommendations made in the following publication (reproduced on the
following pages), which is adopted as an International Standard:
CCSDS 131.4-M-1, July 2011, TM Channel Coding Profiles
For the purposes of international standardization, the modifications outlined below shall apply to the specific
clauses and paragraphs of publication CCSDS 131.4-M-1.
Pages i to vi
This part is information which is relevant to the CCSDS publication only.
Pages 1-2
Add the following information to the reference indicated:
[1] Document CCSDS 131.0-B-2, August 2011, is equivalent to ISO 22641:2012.
3 Revision of publication CCSDS 131.4-M-1
It has been agreed with the Consultative Committee for Space Data Systems that Subcommittee
ISO/TC 20/SC 13 will be consulted in the event of any revision or amendment of publication CCSDS 131.4-M-
1. To this end, NASA will act as a liaison body between CCSDS and ISO.

CCSDS 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 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
voluntary, 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
elements 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 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 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 of 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 encouraged to
direct planning for its new Practices and implementations towards the later version of the
Recommended Practice.
