MSG 1 (Meteosat Second Generation 1) is a European (EUMETSAT consortium) geostationary weather satellite that was launched by an Ariane 5 rocket from Kourou at 22:45 UT on 28 August 2002. The cylindrical, 2-tonne satellite will enable quicker and more accurate weather forecast in Europe than in the past, after first parking over 10 deg-E longitude for six months and later moving to zero degree longitude. It carries two major instruments. Raw data from both instruments will be directly downlinked to Darmstadt, Germany; the processed data will be uplinked to the same satellite to be rebroadcast to Europe and other regions. Besides those two instruments, MSG 1 carries receivers for weather-data from remote/mobile sites, and a 406 MHz transponder for search-and-rescue SOS operations conducted by the global COSPAS-Surat organization.
