Summary of Radio Astronomy issues at WRC-07 (November 30,
2007)
The International Telecommunication Union's 2007 World
Radiocommunicataion Conference (WRC-07) ended earlier this month.
Attached is a summary of issues relevant to radio astronomy that were
addressed by the conference. WRC-07 also established a preliminary
agenda for the next WRC, expected to be held in 2011. The preliminary
WRC-11 agenda items of potential interest to the radio astronomy
community are also summarized in the
attached document. Please feel free
to contact Andrew Clegg, Tom Gergely, or Harvey Liszt for additional
information.

General information
There are many issues regarding spectrum management that are a critical concern to radio astronomy and radio astronomers. The FCC is the major federal organization that regulates and mediates the licensing of the spectrum for civilian use including protection bands and areas in country for passive use such as radio astronomy and earth observations. I am still trying to sort out the relative roles of the FCC and the executive branch's National Telecommunications and Information Administration, or NTIA .
Every two years there is an international gathering, the World Radiocommunication Conference, to decide on global allocation issues. The next WRC is in June 2000. The international body in charge is the International Telecommunications Union, or ITU , with its headquarters in Geneva.
The US radio astronomy observatories commit significant resources to local interference monitoring and reduction and to participation in US and International spectrum management issues that are of vital concern to the future of radio astronomy. At NRAO Green Bank there is a National Radio Quiet Zone ( NRQZ); they have recently established an interference protection group .
The NRAO Very Large Array, VLA, provides a summary of interference in their observing bands, memoranda and Bill Brundage's summary of World Radio Astronomy Frequency Allocations. There is also a summary of RFI at the NRAO Very Long Baseline Array, VLBA sites.
IUCAF, the Scientific Committee on Frequency Allocations for Astronomy and Space Science represents the interests of Radio Astronomy internationally, and in particular at the ITU.
Tapasi Ghosh maintains Arecibo Observatory site information about spectrum management issues and interference monitoring activity at the Arecibo Observatory.
Tom Gergely is head of the Electromagnetic Spectrum Management section of the Division of Astronomical Sciences (AST) which is in the Mathematical and Physical Sciences Directorate (MPS) of the National Science Foundation (NSF). The Electromagnetic Spectrum Manager represents the interests of the U.S. scientific community in the field of telecommunications management and regulation at national, as well as international forums. For additional information refer to AAS Committee on Light Pollution, Radio Interference and Space Debris.
The US National Research Council (NRC) which is part of the National Academy
of Sciences (NAS) has a number of Boards on Physics and Astronomy (BPA).
One of these is the Committee on Radio Frequencies, CORF;
here you will find a set of views, list of US radio observatories, and
links to IUCAF and ITU. There is a link there to the European equivalent
that I will repeat here: the Committee on Radio Astronomy Frequencies or
CRAF . They have issued
a handbook on radio astronomy
with valuable summary of our service. The ITU-R also has a handbook on
Radio Astronomy.
