Its role is to manage the international radio-frequency spectrum and satellite orbit resources and to develop standards for radiocommunication systems with the objective of ensuring the effective use of the spectrum. URSI supports IUCAF, the Steering Committee on Frequency Allocation for Radio Astronomy and Space Science (of which it is a parent Union) and ISES, the International Space Environment Service which provides information relevant to disciplines related to the Sun-Earth environment.The ITU Radiocommunication Sector ( ITU-R) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU) and is responsible for radio communications. In 1990, URSI founded a Scientific Committee on Telecommunications, the objectives of which are to facilitate cooperation between the Commissions of URSI and the ITU for the study of scientific aspects of telecommunications problems. URSI has close contacts with other NGOs and also with IGOs, in particular with the International Telecommunications Union (ITU). URSI’s quarterly magazine The Radio Science Bulletin can be downloaded free of charge from our homepage. In 1993, it established a Network of Correspondents which at present has some 2,100 adherents. to represent radio science to the general public, and to public and private organizations.Īt present, 45 Member Committees adhere to URSI.the generation, emission, radiation, propagation, reception, and detection of fields and waves, and the processing of the signals embedded in them.the scientific aspects of telecommunications using electromagnetic waves, guided and unguided.to stimulate and coordinate studies of:.to encourage the adoption of common methods of measurement, and the intercomparison and standardisation of the measuring instruments used in scientific work.to encourage and promote international activity in radio science and its applications, for the benefit of humanity.Included within the objectives are the following: The International Union of Radio Science (Union Radio Scientifique Internationale), a non-governmental and non-profit organization under the International Council for Science, is responsible for stimulating and coordinating, on an international basis, studies, research, applications, scientific exchange, and communication in the fields of radio science. Radio science encompasses the knowledge and study of all aspects of electromagnetic fields and waves. Its object is now described in Article 1 of the Statutes, namely:Īrticle 1. The original objective of URSI in 1919 (to encourage scientific studies of radiotelegraphy, especially those which require international cooperation) has been broadened considerably over the past 70 years. This had been active during the period 1913-1914, when the only existing type of radio communication was radiotelegraphy. URSI’s origins go back even further, to the earlier International Commission on Scientific Radiotelegraphy. The International Union of Radio Science, universally referred to as URSI (Union Radio-Scientifique Internationale), was created in 1919 during the Constitutive Assembly of the International Research Council (now ISC).
