Radio astronomy telescopes are extremely sensitive and thus very susceptible to radio frequency interference (RFI). With the growth of telecommunication services the RFI is also growing and it’s becoming increasingly critical that radio telescopes are protected from such RFI. Radio frequency usage is regulated by the International Telecommunications Union (ITU) and radio astronomy is allocated bands under the international Radio Regulations. Hence radio astronomy is protection starts internationally at the ITU and spreads to regional and national radio communication and regulation bodies. The radio astronomy community is already involved in all these for a and this involvement needs to be maintained and supported. At the ITU the main forum for radio astronomy protection is Working Party 7D (WP7D), which meets regularly and conduct studies relevant to radio astronomy. It produce ITU Reports and Recommendations that form the technical basis of protection for radio astronomy. WP7D also participates in the preparation for the World Radio communications Conference (WRC) where the Radio Regulations are updated and revised. Inputs to the ITU and the WRC are provided by national administrations and coordinated by regional bodies (APT, CEPT, CITEL). The international advice and advocacy for radio astronomy at the ITU and other international and regional bodies. This activity is also supported by similar regional committees such as CRAF in Europe, CORF in the Americas and RAFCAP in the Asia-Pacific region. An overview of the organization of radio frequency protection for radio astronomy will be given and challenges will be highlighted, especially as pertaining to new instrument like the SKA.
