SFCG is the pre-eminent radio-frequency collegiate
of Space Agencies and related
national and international organizations through which global space
systems spectrum
resources are judiciously husbanded for the benefit of humanity.
Objective
The SFCG was established in order to provide a less formal and
more flexible environment, as compared to the official organs
of
the International Telecommunications Union (ITU) (i.e., Radiocommunication
Bureau (RB); Radio Communication Study Groups (SG) of the Radiocommunication
Bureau), for the solution of frequency management problems encountered
by member space agencies. The Terms of Reference and other aspects
of SFCG organization and procedures may be found in Section II
of the SFCG Handbook.
The SFCG is concerned with the effective use and management of
those radio frequency bands that are allocated by the Radio Regulations
of the ITU to the Space Research, Space Operations, Earth Exploration
Satellite, and Meteorological Satellite services. The Group will
also concern itself with feeder links and data relay satellites
operated in connection with these services, and with satellite-borne
radio astronomy (including radar astronomy). Within the formal framework
of the Radio Regulations, there is the need and opportunity for
international informal agreement among participating space agencies
concerning assignment of specific frequencies, and related technical
issues.
The principal result of SFCG meetings is the adoption of resolutions
and recommendations which express technical and administrative agreements.
These agreements may be used by space agencies to make best use
of allocated bands and to avoid interference.
The effectiveness of SFCG recommendations depends upon voluntary
acceptance and use by member agencies. There is no formal process
by which agencies formally agree to accept and be bound by SFCG
recommendations.
Agency representatives that participate in SFCG meetings are generally
expected to be able to speak for their agencies in an informed way
and to be able to influence compliance with SFCG recommendations.
Admission of new members is governed by Resolution A3-1R3. A listing
of SFCG members and observers may be found on the SFCG
Members page. Application by space agencies for membership
can be made through the submission of a Membership
Application Form.

Charter
Terms of Reference of the Space Frequency Coordination
Group (Resolution A6-1R2)
The SFCG,
NOTING
i) the letter of the Director General of the European Space Agency
(ESA) of 16 January, 1980 in which he proposed the creation of SFCG
and accepted that ESA provide the permanent secretariat;
ii) the importance of periodically updating its Terms of Reference;
CONSIDERING
a) that the Group has successfully conducted annual meetings since
1980;
b) that the Terms of Reference are updated periodically to maintain
current relevance;
RESOLVES
To establish the following Terms of Reference:
SFCG provides a forum for multilateral discussion and coordination
of spectrum matters of mutual interest concerning, in particular,
the following space radiocommunication services, as defined in the
ITU Radio Regulations:
Space research
Space operations
Earth exploration satellite
Meteorological satellite
Inter-satellite
Radionavigation satellite
Radioastronomy and radar astronomy to the extent that they are
relevant to spacecraft missions,
The agreed upon results of SFCG work will be expressed in the form
of Resolutions, Recommendations, or whatever form may be appropriate
for the case. SFCG members will attempt to ensure that findings
of SFCG are taken into account by their agencies.
SFCG will:
facilitate early understanding of present and future plans for
space systems and services and of other systems affecting these;
identify problem areas and coordination needs, and study potential
solutions associated therewith;
identify issues and policy matters relating to the future orderly
use of the frequency bands allocated to respective space radiocommunication
services;
suggest courses of action to be taken by SFCG member agencies
with regard to current and future frequency needs of the space
radiocommunications services identified above,
identify those matters for which member agencies should facilitate
contributions to regional bodies (e.g. APT, CEPT, CITEL), ITU-R
Study Groups; or to encourage their administrations to make proposals
to ITU WRCs;
closely cooperate in the area of frequency management with other
space agencies as well as with commercial or research users of
frequency bands allocated to the services identified above;
consider any other items of technical, operational, or administrative
nature which affect the interests of the Group; and
maintain strong ties with other international bodies with related
objectives.
DECIDES
to accept ESA's offer to provide the permanent Secretariat of the
SFCG.
