MSG

Status: Operational 2002. First Launch: 2002-08-28. Last Launch: 2015-07-15. Number: 4 . Gross mass: 2,000 kg (4,400 lb).

The 3.2m diameter cylindrical satellite had a dry mass of about 1000 kg and carried about 1010 kg of propellant. MSG was to allow quicker and more accurate weather forecasts in Europe than in the past. It carried two major instruments.

• SEVIRI (Spinning Enhanced Visible and Infra-Red Imager) was a 12-channel imager that was to provide a set of surface and cloud-cover images every 15 minutes at a spatial resolution of 1 km. Four of the channels were in cloud- and soil-reflected visible wavelengths, four infrared channels were to measure temperature of clouds and sea-surface, and the remaining four infrared channels were to provide water vapor, ozone and carbon dioxide contents.

• GERB (Geostationary Earth Radiation Budget) measured the radiation coming from the Sun and the reflected/emitted radiation from the Earth to obtain the radiation balance.

The satellite also carried receivers for weather-data from remote/mobile sites, and a 406 MHz transponder for search-and-rescue SOS operations conducted by the global COSPAS-Surat organization.
