12th Plenary Assembly of CCIR (the International Radio Consultative Committee) convened in New Delhi on January 21, 1970, to address technical and operational issues pertaining to radio communication and to formulate recommendations on these matters. These assemblies typically occur approximately every three years.
Established in 1927, the CCIR operates as one of the permanent organs of the International Telecommunication Union (ITU). Its primary mandate involves investigating and advising the ITU on technical and operational aspects related to radio communication, including emerging challenges in space communication.
The CCIR plays a crucial role in establishing agreed-upon technical standards that form the basis for international radio discussions and agreements. It also determines the technical specifications to be recommended for equipment and systems used in international radio communication.
To fulfill its objectives, the CCIR operates through various study groups, each focusing on distinct areas such as radio transmitters and receivers, sound and television broadcasting, radio propagation, international radio monitoring, satellite communication, maritime and aeromobile radio systems, among others. These study groups collaborate to address a wide range of topics relevant to the field of radio communication.
