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 13526 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as
CCSDS 503.0-B-1, November 2007) 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 RECOMMENDED STANDARD FOR TRACKING DATA MESSAGE
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.

CCSDS RECOMMENDED STANDARD FOR TRACKING DATA MESSAGE
FOREWORD
This document is a Recommended Standard for tracking data messages and has been
prepared by the Consultative Committee for Space Data Systems (CCSDS). The tracking
data message described in this Recommended Standard is the baseline concept for tracking
data interchange applications that are cross-supported between Agencies of the CCSDS.
This Recommended Standard establishes a common framework and provides a common
basis for the format of tracking data exchange between space agencies. It allows
implementing organizations within each Agency to proceed coherently with the development
of compatible derived standards for the flight and ground systems that are within their
cognizance. Derived Agency standards may implement only a subset of the optional features
allowed by the Recommended Standard and may incorporate features not addressed by this
Recommended Standard.
Through the process of normal evolution, it is expected that expansion, deletion or
modification to this document may occur. This Recommended Standard 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. 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 RECOMMENDED STANDARD FOR TRACKING DATA MESSAGE
1 INTRODUCTION
1.1 PURPOSE
1.1.1 This Tracking Data Message (TDM) Recommended Standard specifies a standard
message format for use in exchanging spacecraft tracking data between space agencies. Such
exchanges are used for distributing tracking data output from routine interagency cross-
supports in which spacecraft missions managed by one agency are tracked from a ground
station managed by a second agency. The standardization of tracking data formats facilitates
space agency allocation of tracking sessions to alternate tracking resources. This
Recommended Standard has been developed via consensus of the Navigation Working
Group of the CCSDS Mission Operations and Information Management Services (MOIMS)
area.
1.1.2 This document includes requirements and criteria that the message format has been
designed to meet. For exchanges where these requirements do not capture the needs of the
participating Agencies another mechanism may be selected.
1.2 SCOPE AND APPLICABILITY
1.2.1 This Recommended Standard contains the specification for a Tracking Data Message
designed for applications involving tracking data interchange between space data systems.
Tracking data includes data types such as Doppler, transmit/received frequencies, range,
angles, Delta-DOR, DORIS, PRARE, media correction, weather, etc. The rationale behind the
design of the message is described in annex F and may help the application engineer construct a
suitable message. It is acknowledged that this version of the Recommended Standard may not
apply to every single tracking session or data type; however, it is desired to focus on covering
approximately the ‘95% level’ of tracking scenarios, and to expand the coverage in future
versions as experience with the TDM is gained.
1.2.2 This message is suited to inter-agency exchanges that involve automated interaction.
The attributes of a TDM make it primarily suitable for use in computer-to-computer
communication because of the large amount of data typically present. The TDM is self-
contained, with no additional information required beyond that specified in an Interface
Control Document (ICD) written jointly by the service provider and customer agency.
1.2.3 Definition of the accuracy pertaining to any particular TDM is outside the scope of
this Recommended Standard and should be specified via an Interface Control Document
(ICD) between data exchange participants.
1.2.4 This Recommended Standard is applicable only to the message format and content, but
not to its transmission. The method of transmitting the message between exchange partners is
beyond the scope of this document and should be specified in the ICD. Message transmission
could be based on a CCSDS data transfer protocol, file based transfer protocol such as SFTP,
stream-oriented media, or other secure transmission mechanism. In general, the transmission
mechanism must not place constraints on the technical data content of a TDM.

ISO 13526:2010(E)
CCSDS RECOMMENDED STANDARD FOR TRACKING DATA MESSAGE
1.2.5 There are some specific exclusions to the TDM, as listed below:
1.2.5.1 Satellite Laser Ranging (SLR) ‘Fullrate’ and/or ‘Normal Points’ format (sometimes
referred to as ‘Quicklook’), which are already transferred via a standardized format
documented at http://ilrs.gsfc.nasa.gov/;
1.2.5.2 Exchanges of raw Global Navigation Satellite System (GNSS) data, which is
standardized via the RINEX format (http://gps.wva.net/html.common/rinex.html);
1.2.5.3 Global Positioning Satellite (GPS) navigation solutions, which are standardized via
1
the SP3 format (http://www.ngs.noaa.gov/GPS/GPS.html);
1.2.5.4 Optical data from navigation cameras (pixel based, row-column, etc.);
1.2.5.5 LIDAR data (which may include a laser range finder); however, such data could
conceivably be transferred via TDM with a ‘RANGE’ keyword (see 3.5.2.6); and
1.2.5.6 Altimeter data; however, such data could conceivably be transferred via TDM with
a ‘RANGE’ keyword (see 3.5.2.6).
1.2.6 Description of the message format based on the use of eXtensible Markup Language
(XML) is detailed in an integrated XML schema document for all Navigation Data Message
Recommendations: Attitude Data Messages (ADM), Orbit Data Messages (ODM), and
Tracking Data Message (TDM). See reference [E8].
1.3 CONVENTIONS AND DEFINITIONS
1.3.1 Conventions and definitions of navigation concepts such as reference frames, time
systems, etc., are provided in reference [1].
1.3.2 The following conventions apply throughout this Recommended Standard:
– the words ‘shall’ and ‘must’ imply a binding and verifiable specification;
– the word ‘should’ implies an optional, but desirable, specification;
– the word ‘may’ implies an optional specification;
– the words ‘is’, ‘are’, and ‘will’ imply statements of fact.
1
It has been suggested that the statement regarding navigation solutions being standardized by SP3 is not
correct, because SP3 prescribes equidistant data (ephemerides), which are in general not provided by each
GPS/GNSS receiver. It was proposed that the navigation solution data (epoch, x, y, z, v , v , v ) should be
x y z
provided in the TDM, with the velocities as optional values. However, this would require major changes to the
TDM that are contrary to its intended purpose. As an alternative, the CCSDS Orbit Data Messages OEM (Orbit
Ephemeris Message) (reference [4]) could be used to convey the navigation solution if all position and velocity
components are transferred. The OEM is already set up to convey all the required values, and can be used to
convey orbit reconstructions as well as orbit predictions.

– The word ‘participant’ denotes an entity that has the ability to acquire or broadcast
navigation messages and/or radio frequencies, for example, a spacecraft, a quasar, a
tracking station, a tracking instrument, or an agency.
– The term ‘n/a’ or ‘N/A’ denotes an attribute that is not applicable or not available.
1.3.3 The following conventions for unit notations apply throughout this Recommended
Standard. Insofar as possible, an effort has been made to use units that are part of the
International System of Units (SI Units); units are either SI base units, SI derived units, or
units outside the SI that are accepted for use with the SI (see reference [8]). There are a
small number of specific cases where units that are more widely used in the navigation
community are specified, but every effort has been made to minimize these departures from
the SI.
