The Arab Satellite Communications Organization (often abbreviated as Arabsat) is a leading communications satellite operator in the Arab World, headquartered in the city of Riyadh, Saudi Arabia. Arabsat was created to deliver satellite-based, public and private telecommunications services to the Arab States, in accordance with International Standards. With more than 20 member countries, the organization plays a vital role of enhancing communications in the Arab World.〔(【引用サイトリンク】title=Emir of Kuwait Adorns Arab Sat Informatics Medal 2009 )〕 The Arabsat satellites are a series of geostationary communications satellites launched from 1985 through 2011. Some of the later satellites in the series remain operational in orbit, while others have been retired and are . ==History== The foundation of Arab Satellite Communications Organization (Arabsat) dates back to the end of the 1960s. In 1967, information ministers of Arab states developed a series of principles in relation to a satellite network. The goal of this network was to create an integration among the countries of the Arab League in terms of the social and cultural activities. On the other hand, the Arab States Broadcasting Union (ASBU) was established in 1969. Saudi Arabia did not join this Egypt-led and Cairo-based union until 1974, most probably due to the tense relationship between Saudi Arabia and Egypt at the time. On April 14, 1976, Arabsat was formed under Arab League jurisdiction with the goal of serving the information, cultural and educational needs of its member states. Saudi Arabia was the main financier of the new organization due to its expanded financial resources as a result of oil-boom period and Riyadh housed Arabsat's headquarters.〔 The first launch Arabsat-1A was performed by a French Ariane rocket. The U.S. space shuttle ''Discovery'' launched Arabsat's second satellite, Arabsat-1B, in 1985. Arabsat-1A and -1B were switched off in 1992 and 1993, respectively.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arab Satellite Communications Organization」の詳細全文を読む スポンサード リンク
