ISO 26900:2012

Space data and information transfer systems — Orbit data messages

ISO 26900:2012 specifies three standard message formats for use in transferring spacecraft orbit information between space agencies and commercial or governmental spacecraft operators: the Orbit Parameter Message (OPM), the Orbit Mean-Elements Message (OMM), and the Orbit Ephemeris Message (OEM). Such exchanges are used for a) pre-flight planning for tracking or navigation support, b) scheduling tracking support, c) carrying out tracking operations (sometimes called metric predicts), d) performing orbit comparisons, e) carrying out navigation operations such as orbit propagation and orbit reconstruction, f) assessing mutual physical and electromagnetic interference among satellites orbiting the same celestial body (currently primarily Earth, Moon, and Mars), g) performing orbit conjunction (collision avoidance) studies, and h) developing and executing collaborative manoeuvres to mitigate interference or enhance mutual operations. ISO 26900:2012 includes sets of requirements and criteria that the message formats have been designed to meet.

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 26900 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as
CCSDS 502.0-B-2, November 2009) 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 14, Space systems and operations, in collaboration with SC 13, Space data and information transfer
systems.
ISO 26900 cancels and replaces ISO 22644:2006, which has been technically revised.
This corrected version of ISO 26900:2012 also incorporates the corrections of Technical Corrigendum
CCSDS 502.0-B-2 Cor. 1, May 2012. Corrections are identified in the enclosed CCSDS publication by a bar in
the margin and the designation "Cor. 1". In addition, the list of equivalent references in Clause 2 of this
International Standard has been updated.

INTERNATIONAL STANDARD ISO 26900:2012(E)

Space data and information transfer systems — Orbit data
messages
1 Scope
This International Standard specifies three standard message formats for use in transferring spacecraft orbit
information between space agencies and commercial or governmental spacecraft operators: the Orbit
Parameter Message (OPM), the Orbit Mean-Elements Message (OMM), and the Orbit Ephemeris Message
(OEM). Such exchanges are used for
a) pre-flight planning for tracking or navigation support,
b) scheduling tracking support,
c) carrying out tracking operations (sometimes called metric predicts),
d) performing orbit comparisons,
e) carrying out navigation operations such as orbit propagation and orbit reconstruction,
f) assessing mutual physical and electromagnetic interference among satellites orbiting the same celestial
body (currently primarily Earth, Moon, and Mars),
g) performing orbit conjunction (collision avoidance) studies, and
h) developing and executing collaborative manoeuvres to mitigate interference or enhance mutual
operations.
This International Standard includes sets of requirements and criteria that the message formats have been
designed to meet.
NOTE For exchanges where these requirements do not capture the needs of the participating agencies and satellite
operators, another mechanism can be selected.
The scope and field of application are furthermore detailed in subclauses 1.1 and 1.2 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:
