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-1, September 2003) 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.

CCSDS RECOMMENDATION 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 member space Agencies. 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 considered binding on any Agency.
This Recommendation is issued by, and represents the consensus of, the CCSDS Plenary
body. Agency endorsement 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 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.
– Specific service arrangements are 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 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 Recommendation is issued, existing CCSDS-
related Agency standards and implementations are not 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 standards and implementations towards the later version of the
Recommendation.

CCSDS RECOMMENDATION FOR COMMUNICATIONS OPERATION PROCEDURE-1

FOREWORD
This document is a technical Recommendation 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 Recommendation 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 Recommendation has been developed from an existing CCSDS
Recommendation that specifies Command Operation Procedure-1 (reference [B2]), which
defines essentially the same procedure but in a slightly different context.
This Recommendation does not change the basic technical contents defined in [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 Recommendation, 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 [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 Recommendations
that define space link protocols. These changes are listed in annex D of this
Recommendation.
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 management and change control procedures, as defined in the Procedures
Manual for the Consultative Committee for Space Data Systems [B1]. Current versions of
CCSDS documents 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.

CCSDS RECOMMENDATION FOR COMMUNICATIONS OPERATION PROCEDURE-1

1 INTRODUCTION
1.1 PURPOSE
The purpose of this Recommendation is to specify the Communications Operation
Procedure-1 (COP-1). This procedure is used with the Telecommand (TC) Space Data Link
Protocol [3] 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.
It is assumed that the reader of this document is familiar with the data structures and
terminology contained in reference [3].
1.2 SCOPE
This Recommendation 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.
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.
In case of conflict between reference [3] and this Recommendation, this Recommendation
will take precedence.
1.3 APPLICABILITY
This Recommendation applies to the creation of Agency standards and to the future data
communications over space links between CCSDS Agencies in cross-support situations.
This Recommendation includes comprehensive specification of the procedure for inter-
Agency cross support. It is neither a specification of, nor a design for, real systems that may
be implemented for existing or future missions.
The Recommendation specified in this document is to be invoked through the normal
standards programs of each CCSDS Agency, and is applicable to those missions for which

---------------------- Page: 16 ----------------------
ISO 22667:2005(E)
CCSDS RECOMMENDATION FOR COMMUNICATIONS OPERATION PROCEDURE-1

cross support, based on capabilities described in this Recommendation, is anticipated.
Where mandatory capabilities are clearly indicated in sections of this Recommendation, they
must be implemented when this document is used as a basis for cross support. Where
options are allowed or implied, implementation of these options is subject to specific
bilateral cross support agreements between the Agencies involved.
This Recommendation is applicable only to those Projects that implement the TC Space Data
Link Protocol [3].
1.4 RATIONALE
The CCSDS believes it is important to document the rationale underlying the
recommendations chosen, so that future evaluations of proposed changes or improvements
will not lose sight of previous decisions.
1.5 DOCUMENT STRUCTURE
This document is divided into seven numbered sections and three annexes:
a) section 1 presents the purpose, scope, applicability and rationale of this
Recommendation and lists the conventions, definitions, and normative references
used throughout the Recommendation;
b) section 2 provides an overview of the COP-1;
c) section 3 describes the interfaces between COP-1 and the other procedures used in
the TC Space Data Link Protocol;
d) section 4 describes the detailed service definition related to COP-1, and complements
the service definition of reference [3];
e) section 5 specifies the Frame Operation Procedure-1 (FOP-1), which is the procedure
used at the sending side of COP-1;
f) section 6 specifies the Frame Acceptance and Reporting Mechanism-1 (FARM-1),
which is the procedure used at the receiving side of COP-1;
g) section 7 specifies the managed parameters used by COP-1;
h) annex A lists all acronyms used within this document;
i) annex B provides a list of informative references;
j) annex C shows the format of the state tables used in sections 5 and 6;
k) annex D lists the changes contained in this Recommendation as compared to the
previously issued CCSDS COP Recommendation [B2].
