Just what do the letters IUCAF stand for?
• IUCAF used to stand for
“Inter-Union Commission on the Allocation of Frequencies
for Space Research and Radio Astronomy”
• The title was later changed to
“Scientific Committee on Frequency Allocations for Radio
Astronomy and Space Science”
But “IUCAF” had become so well known that it was
decided to keep the same acronym.
In 1960 ICSU set up the Inter-Union
Commission “IUCAF” to work towards
keeping parts of the radio spectrum clear
for passive, scientific use.
• Represents URSI, the IAU and COSPAR at the
International Telecommunications Union (ITU).
• Formation was partly prompted by the potential
threat from Project WEST FORD. (Needles in
orbit).
• In 1961 CORF was established “to serve as the
United States counterpart to IUCAF.”

“IUCAF members had to evolve from being starry-eyed
astronomers as they encountered a world of politics,
lobbying, entertainment, threats, espionage and bribery.
On one occasion, an offer (in Geneva) of two million
dollars in cash “to shut up” proved no match for
dedication to the joys and excitement of twentiethcentury astrophysics.”
Brian Robinson, “Frequency Allocation: The First Forty Years.”
Ann Rev. Astron. Astrophys. 1999, 37:65-96
