Model of MSG

The Meteosat series of satellites are geostationary meteorological satellites operated by EUMETSAT under the Meteosat Transition Programme and the Meteosat Second Generation 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, which came into operation at the start of 2004 using improved satellites. The MSG program will provide service until the MTG program takes over.
