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.
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 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 identifying any or all such patent rights.
ISO 22667 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as
CCSDS 232.1-B-2, September 2010) and was adopted (without modifications except those stated in Clause 2
of this International Standard) by Technical 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 22667:2005), which has been technically
revised.
INTERNATIONAL STANDARD ISO 22667:2013(E)

Space data and information transfer systems —
Communications operation procedure-1
1 Scope
1.1 This International Standard specifies the communications operation procedure-1 (COP-1). This
procedure is used with the telecommand (TC) space data link protocol (as defined in ISO 22664:2013) to
enable the delivery of service data units to the receiving end of the layer above, correct and without omission
or duplication, and in the same sequential order in which they were received from the layer above at the
sending end.
1.2 This International Standard defines the COP-1 in terms of
a) the interfaces with the other procedures,
b) the internal variables used by the protocol entity,
c) the actions performed by the protocol entity, and
d) the state transitions of the protocol entity.
1.3 It does not specify
a) individual implementations or products,
b) the implementation of service interfaces within real systems,
c) the methods or technologies required to perform the procedures, or
d) the management activities required to configure and control the protocol.
1.4 The scope and field of application are furthermore detailed in subclauses 1.1, 1.2 and 1.3 of the
enclosed CCSDS publication.
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 232.1-B-2, September 2010, Communications operation procedure-1.
For the purposes of international standardization, the modifications outlined below shall apply to the specific
clauses and paragraphs of publication CCSDS 232.1-B-2.
Pages i to vi
This part is information which is relevant to the CCSDS publication only.

Add the following information to the reference indicated:
[3] Document CCSDS 232.0-B-2, July 2010, is equivalent to ISO 22664:2013.
3 Revision of publication CCSDS 232.1-B-2
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 232.1-
B-2. To this end, NASA will act as a liaison body between CCSDS and ISO.

This document has been approved for publication by the Management Council of the

technical agreement of the participating CCSDS Member Agencies. The procedure for
review and authorization of CCSDS documents is detailed in the Procedures Manual for the
Consultative Committee for Space Data Systems, and the record of Agency participation in
the authorization of this document can be obtained from the CCSDS Secretariat at the

RECOMMENDED STANDARD FOR COMMUNICATIONS OPERATION PROCEDURE-1
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 Recommended Standards and are not
considered binding on any Agency.
This Recommended Standard is issued 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 Standard. 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 operational 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, this 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 Recommended 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 direct planning for its new standards and implementations towards the later
version of the Recommended Standard.

RECOMMENDED STANDARD FOR COMMUNICATIONS OPERATION PROCEDURE-1
FOREWORD
This document is a technical Recommended Standard 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 Communications Operation Procedure-1 (COP-1) described
herein is intended for missions that are cross-supported between Agencies of the CCSDS.
This Recommended Standard specifies an automatic retransmission procedure to be used by
space missions to transfer space application data over a ground-to-space or space-to-space
communications link. This Recommended Standard has been developed from an existing
CCSDS Recommended Standard that specifies Command Operation Procedure-1
(reference [B2]), which defines essentially the same procedure but in a slightly different
context.
This Recommended Standard does not change the basic technical contents defined in
reference [B2], but the name of the procedure and the presentation of the specification have
been changed so that:
a) COP-1 can be used to transfer any data over any space link in either direction;
b) the specification matches the Open Systems Interconnection (OSI) Basic Reference
Model (references [2] and [3]).
The most notable change in presentation is that COP-1 is defined as a procedure in the Data
Link Layer of the OSI Model in this Recommended Standard, whereas it is defined as a
procedure in the Transfer Layer (a sublayer of the Data Link Layer) in reference [B2].
Together with the change in presentation, a few technical details in reference [B2] have been
changed based upon experience in using this procedure. Also, some technical terms in
reference [B2] have been changed in order to unify the terminology used in all CCSDS
Recommended Standards that define space link protocols. These changes are listed in
annex D of this Recommended Standard.
Through the process of normal evolution, it is expected that expansion, 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 documents are maintained at the CCSDS Web site:

Questions relating to the contents or status of this document should be addressed to the
CCSDS Secretariat at the address indicated on page i.
