The European Telecommunications Satellite Organization (EUTELSAT IGO) is an intergovernmental organisation consisting of 49 member states. Its mission is to maintain the rights to use radio frequencies and orbital locations which were assigned collectively to the Member States by the International Telecommunication Union and to oversee the operations of Eutelsat S.A. so as to ensure that the company complies with the EUTELSAT Amended Convention. Other key activities of EUTELSAT IGO include ongoing monitoring of the regulatory environment in European countries and continued collaboration with other international organisations. EUTELSAT IGO has the status of an International Organization Operating Satellite Systems (IOOSS) in all three sectors of the ITU. Since June 2008, EUTELSAT IGO has also held permanent Observer status with the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS). The organisation also cooperates with other satellite organisations such as International Telecommunications Satellite Organisation (ITSO), International Mobile Satellite Organisation (IMSO) and INTERSPUTNIK. EUTELSAT IGO consists of the Assembly of Parties to the EUTELSAT Convention and the Secretariat which is the permanent body of the Organisation.
