The Meteosat series of satellites are geostationary meteorological satellites operated by EUMETSAT under the Meteosat Transition Programme (MTP) and the Meteosat Second Generation (MSG) program. The MTP program was established to ensure the operational continuity between the end of the successful Meteosat Operational Programme in 1995 and Meteosat Second Generation (MSG), which came into operation at the start of 2004 using improved satellites. The MTP provides an overlap with MSG by continuing the current Meteosat system until at least the end of the year 2005. The MSG program will provide service until the MTG (Meteosat Third Generation) program takes over. ==First generation== The first generation of Meteosat satellites, Meteosat-1 to Meteosat-7, provide continuous and reliable meteorological observations from space to a large user community. In addition to the provision of images of the Earth and its atmosphere every half-hour in three spectral channels (Visible, Infrared) and Water Vapour, via the Meteosat Visible and Infrared Imager (MVIRI) instrument, a range of processed meteorological products is produced. Meteosat also supports the retransmission of data from data collection platforms in remote locations, at sea and on board aircraft, as well as the dissemination of meteorological information in graphical and text formats. The satellites were manufactured by a consortium COSMOS, with Aérospatiale in its Cannes Mandelieu Space Centre, as Prime, and included Matra, MBB, Selenia Spazio, Marconi Company. They are 2.1 metres in diameter and 3.195 metres long. Its initial mass in orbit is 282 kg, and in orbit, the satellite spins at 100 rpm around its main axis 〔(EUMETSAT - MFG Architecture )〕 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「Meteosat」の詳細全文を読む スポンサード リンク
