Minimize Meteosat Second Generation
Web Content Image

The Meteosat Second Generation (MSG) consists of a series of four geostationary meteorological satellites, along with ground-based infrastructure, that will operate consecutively until 2020. The MSG satellites carry an impressive pair of instruments - the Spinning Enhanced Visible and InfraRed Imager (SEVIRI), which has the capacity to observe the Earth in 12 spectral channels and provide image data which is core to operational forecasting needs, and the Geostationary Earth Radiation Budget (GERB) instrument supporting climate studies.

For almost 30 years ESA has been building Europe's orbital weather satellites: the Meteosat series of geostationary spacecraft, the first of which was launched in 1977. The success of the early Meteosats led to the creation of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) in 1986.

ESA was responsible for designing and developing the first MSG satellite, and for procuring the other three on behalf of EUMETSAT. Meanwhile EUMETSAT has responsibility for defining the payload based on user needs, procuring the ground segment and launchers, and operating the system.

Forty years of Meteosat

22 November 2017

ESA's first Earth observation satellite was launched on 23 November 1977. When the first Meteosat satellite took its place in the sky, it completed coverage of the whole globe from geostationary orbit and laid the foundations for European and world cooperation in meteorology that continues today.

Shared vision strengthens Europe's space strategy

08 November 2017

Working together for three decades, ESA and Eumetsat have been instrumental in positioning Europe as a leader in observing Earth from space. Continuing to share a vision, the two organisations have signed a statement that will strengthen Europe in meteorology and climate monitoring, and that will help to take the Copernicus programme into the future.
