Space data and information transfer systems — Conjunction data message
ISO 19389:2014 specifies a standard message format for use in exchanging spacecraft conjunction information between originators of Conjunction Assessments (CAs) and satellite owner/operators and other authorized parties. Such exchanges are used to inform satellite owner/operators of conjunctions between objects in space to enable consistent warning by different organizations employing diverse CA techniques. ISO 19389:2014 will: facilitate interoperability and enable consistent warning between data originators who supply CA and the satellite owner/operators who use it; facilitate automation for the CA processes; and provide critical information to enable timely CA decisions. This document includes requirements and criteria that the message format has been designed to meet (see Annex D). Also included are informative descriptions of conjunction information pertinent to performing CA (see Annex E). ISO 19389:2014 is applicable to satellite operations in all environments in which close approaches and collisions among satellites are concerns. It contains the specification for a Conjunction Data Message (CDM) designed for applications involving conjunction information interchange between originators of CAs and recipients. Conjunction information includes data types such as miss distance, probability of collision, Time of Closest Approach (TCA), and closest approach relative position and velocity. Further information describing the conjunction information contained in this message can be found in section 3 and Annex E. This message is suited for exchanges that involve manual or automated interaction. The attributes of a CDM make it suitable for use in machine-to-machine interfaces because of the large amount of data typically present. The CDM is self contained. However, additional information could be specified in an Interface Control Document (ICD) written jointly by the service originator and recipients. It is desirable that CDM originators maintain consistency with respect to the optional keywords provided in their implementations; i.e., it is desirable that the composition of the CDMs provided not change on a frequent basis. ISO 19389:2014 is applicable only to the message format and content, but not to its transmission nor to the algorithms used to produce the data within. The method of transmitting the message between exchange partners is beyond the scope of this document and could be specified in an ICD. The methods used to predict conjunctions and calculate the probability of collision, and the definition of the conjunction assessment accuracy underlying a particular CDM, are also outside the scope of ISO 19389:2014 (the interested reader can consult references in Annex F).

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

Space data and information transfer systems — Conjunction
data message
1 Scope
This Conjunction Data Message (CDM) International Standard specifies a standard message format for use in
exchanging spacecraft conjunction information between originators of Conjunction Assessments (CAs) and
satellite owner/operators and other authorized parties. Such exchanges are used to inform satellite
owner/operators of conjunctions between objects in space to enable consistent warning by different
organizations employing diverse CA techniques.
This International Standard will:
a) facilitate interoperability and enable consistent warning between data originators who supply CA and the
satellite owner/operators who use it;
b) facilitate automation for the CA processes; and
c) provide critical information to enable timely CA decisions.
This document includes requirements and criteria that the message format has been designed to meet (see
Annex D). Also included are informative descriptions of conjunction information pertinent to performing CA
(see Annex E).
This International Standard is applicable to satellite operations in all environments in which close approaches
and collisions among satellites are concerns. It contains the specification for a CDM designed for applications
involving conjunction information interchange between originators of CAs and recipients. Conjunction
information includes data types such as miss distance, probability of collision, Time of Closest Approach
(TCA), and closest approach relative position and velocity. Further information describing the conjunction
information contained in this message can be found in section 3 and Annex E.
This message is suited for exchanges that involve manual or automated interaction. The attributes of a CDM
make it suitable for use in machine-to-machine interfaces because of the large amount of data typically
present. The CDM is self contained. However, additional information could be specified in an Interface Control
Document (ICD) written jointly by the service originator and recipients.
It is desirable that CDM originators maintain consistency with respect to the optional keywords provided in
their implementations; i.e., it is desirable that the composition of the CDMs provided not change on a frequent
basis.
This International Standard is applicable only to the message format and content, but not to its transmission
nor to the algorithms used to produce the data within. The method of transmitting the message between
exchange partners is beyond the scope of this document and could be specified in an ICD.
The methods used to predict conjunctions and calculate the probability of collision, and the definition of the
conjunction assessment accuracy underlying a particular CDM, are also outside the scope of this International
Standard (the interested reader can consult references in Annex F).

CCSDS RECOMMENDED STANDARD FOR CONJUNCTION DATA MESSAGES
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 three 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.

CCSDS RECOMMENDED STANDARD FOR CONJUNCTION DATA MESSAGES
FOREWORD
This document is a Recommended Standard for Conjunction Data Messages (CDMs) and has
been prepared by the CCSDS. The CDM described in this Recommended Standard is the
baseline concept for conjunction information interchange applications between interested
parties.
This Recommended Standard establishes a common framework and provides a common
basis for the format of conjunction information exchange between originators of conjunction
assessment data and satellite owner/operators. It allows implementing organizations within
each conjunction assessment originator to proceed coherently with the development of
compatible derived standards for the flight and ground systems that are within their
cognizance. Derived Agency standards can implement only a subset of the optional features
allowed by the Recommended Standard and can incorporate features not addressed by this
Recommended Standard.
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights. CCSDS shall not be held responsible for identifying any or all such
patent rights.
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
Organization and Processes for the Consultative Committee for Space Data Systems
(CCSDS A02.1-Y-3). Current versions of CCSDS documents are maintained at the CCSDS
Web site:
