Under this task focuses on two technica groups the European radio astronomy institutes collaborate as CRAF to coordinate activities to keep the bands used by radio astronomy free from interference and to have a common voice in the international frequency management arena.
The members of CRAF are delegated from radio astronomy institutes in 20 countries in Europe and from South Africa as well as from organizations such as SKA, ESA, IVS and IRAM. They are involved in spectrum management for radio astronomy and as such represent their institutes in national and international issues to protect and maintain the radio spectrum infrastructure. The member institutes bring together the money to employ one frequency manager who represents radio astronomy at many international meetings.
