  skos:definition """This radiometer is the main instrument on board the Meteosat Second Generation  (MSG). MSG is a cooperation program of ESA (European Space Agency) and EUMETSAT (European Organisation for the Exploitation of Meteorological Satellites). This multi-wavelength camera, called SEVIRI, provides images of the Earth disc with cloud, land, ocean, snow and other information made visible by day and by night. It takes one full resolution image every 15 minutes, thus illustrating the weather in motion. Its operating principle is based on collecting the Earth&#039;s radiation by means of a telescope and focusing it on detectors sensitive to 12 different bands of the electromagnetic spectrum. This is followed by the electronic processing of the signals provided by the detectors.

The infrared channels require low detector temperature and hence a large passive cooler. The instrument&#039;s overall mass is 270 kg and its power consumption is nominally less than 123 W during operations.
