The ITU Radiocommunication Sector (ITU-R) plays a vital role in the global
management of the radio-frequency spectrum and satellite orbits - limited
natural resources which are increasingly in demand from a large and growing
number of services such as fi xed, mobile, broadcasting, amateur, space
research, emergency telecommunications, meteorology, global positioning
systems, environmental monitoring and communication services - that ensure
safety of life on land, at sea and in the skies.
ITU-R offers the documents, recommendations, questions, study programs,
resolutions, opinions, and decisions relating to the radiocommunications
including satellites, frequencies, transmission of sound broadcasting,
television signals, and more.
