MSG-4 is a geosynchronous weather satellite from the European operator Eumetsat from the " Meteosat Second Generation" series. The satellite is stationed at 0 °. On February 20, 2018, it began its full service under the name Meteosat-11 , replacing its predecessor Meteosat-10 .
Mission history
MSG-4 was launched on July 15, 2015 at 21:42 ( UTC ) with the Ariane 5 ECA launcher from the Center Spatial Guyanais together with the Star One C4 communications satellite and placed in geostationary orbit at 3.4 ° West. The ESA was responsible for the launch and deployment testing and handed over the satellite on July 27, 2015 Eumetsat. The first image from the satellite was transmitted on August 4, 2015. MSG-4 was in reserve until 2017. The satellite was moved to the 0 ° position and activated at the end of 2017. Since February 20, 2018, it has been recording the entire earth disk from its 0 ° position.
technology
The spin-stabilized satellite provides meteorological data for Europe, Africa (including Réunion ), the Atlantic Ocean and the east of South America. The main instrument of the satellite is the 270 kg Spinning Enhanced Visible and Infrared Imager (SEVIRI), which creates images of the Earth's surface and atmosphere in twelve different wavelengths every 15 minutes. Four of the twelve channels work in the visible range, while the remaining eight monitor the infrared radiation . One of the channels in the visible range has a resolution of 1 km, while the other eleven each have a resolution of 3 km. The data is continuously sent to the ground stations in the L-band . The energy supply is provided by eight curved solar cell surfaces 2.4 m high and 1.25 m wide, which deliver a total of 720 W, and two nickel-cadmium batteries . The satellite was built on the basis of the MSG-FM4 satellite bus from Thales Alenia Space and has a planned service life of 7 years.
