  1. IUCAF Scientific Committee on Frequency Allocations for Radio Astronomy and Space Science formerly known as the Inter-Union Commission on the Allocation of Frequencies for Space Research and Radio Astronomy

  2. The brief of IUCAF To study and coordinate the requirements of radio frequency allocations for passive radio sciences, such as radio astronomy, space research and remote sensing, in order to make these requirements known to the national and international bodies that allocate frequencies.

  3. The “Inter-Union” aspect of IUCAF • Created in 1960 by ICSU (International Council for Science), a non-governmental organisation, representing 101 national scientific bodies and 27 international scientific unions that • coordinates interdisciplinary research • helps create international networks • in close relationship with, e.g., UNESCO • IUCAF is an interdisciplinary body of ICSU • Sponsoring ICSU Scientific Unions: • COSPAR space science • IAU astronomy • URSI radio science

  4. IUCAF’s place in the spectrum management problem space

  5. IUCAF’s place in the worldwide spectrum management circus IUCAF COSPAR Committee on Space Research IAUInternational Astronomical Union URSI International Union of Radio Science CORF Committee on Radio Frequencies (USA) CRAF Committee on Radio Astronomical Frequencies (EUR) RAFCAP Radio Astronomy Frequency Committee in the Asia-Pacific Region ICSU International Council of Scientific Unions ITU International Telecommunication Union RA Radiocommunication Assembly SG 7 Radiocommunication Study Group7 WRC World Radiocommunication Conference

  6. IUCAF activities • Participate in meetings: • - ITU-R (as Sector Member): • 7D (RAS), TG1/8 (UWB), 1/9 (unwanted em.) & WRC’s • - SFCG (as observer) • Organise three-yearly: • Workshop on RFI Mitigation (Penticton, 2004) • Summer school on Spectrum Management (Bologna, 2005) • Yearly budget: ~8 000 EUR (travel grants); • can apply for ICSU grants for organising • international, interdisciplinary activities.

  8. ICSU review of IUCAF in 2004 On its role as an interdisciplinary committee: IUCAF noted the difficulty to find active COSPAR members, and that its members are mainly radio astronomers. ICSU Report: “ICSU should encourage IAU, URSI and COSPAR to organize a joint meeting to define specific procedures and actions that will ensure that IUCAF becomes a truly interdisciplinary committee that has the necessary expertise to coordinate the efforts of all the passive radio sciences in frequency management matters”
