The International Telecommunication Union (ITU) has 3 sectors. The Radiocommunication sector (ITU-R) deals with all systems that make use of radio waves. The Telecommunication Standardization Sector (ITU-T) is dealing with international tariffs, treaties and standardization of wired communicated systems. The Study Group 7 (SG 7) is called Science services and deals with Space research, Radio Astronomy and Earth Observation and Meteorological Systems, and its Working Party 7A deals with all Standard Frequency and Time Signal (SFTS) emissions and transfers, also by satellite and other means.
