Meteosat-11

Meteosat-11 operates from a geostationary position at 0 degrees longitude over the equator, providing continuous weather imagery of Europe, Africa, the Atlantic Ocean, and surrounding regions. It served as the prime operational satellite in EUMETSAT's Meteosat Second Generation system.

Meteosat-11, also designated MSG-4, was launched on July 15, 2015, from French Guiana aboard an Ariane 5 rocket. It became EUMETSAT's prime operational satellite over the 0-degree slot in 2018 and continues to function as of the mid-2020s.

Meteosat-11's primary instrument is the Spinning Enhanced Visible and Infrared Imager (SEVIRI), which images the full Earth disc in 12 spectral channels every 15 minutes at resolutions of 1 to 3 kilometers. It also carries the Geostationary Earth Radiation Budget (GERB) instrument, which measures the balance between incoming solar radiation and outgoing Earth-emitted radiation.

Meteosat-11 belongs to the Meteosat Second Generation series, which provides imagery in 12 spectral channels every 15 minutes. The Meteosat Third Generation (MTG) series, whose first imaging satellite MTG-I1 launched in 2022, offers significantly improved spatial resolution, faster imaging cycles, additional spectral bands, and for the first time, a lightning imager from geostationary orbit.
