Class: Earth. Type: Weather. Nation: Europe. Agency: ESA.

European Space Agency weather satellite. Operational geostationary Meteosat satellites followed 3 pre-operational versions (Meteosat-1,-2,-3/P2). The primary goal of the Meteosat satellites were (1) to provide visible and IR day/night cloud cover data and radiance and (2) disseminate image data to users through the Data Collection Platform (DCP). Meteosats had a 2.1 m diameter, 3.195 m high stepped cylindrical body with solar cells on six main body panels. The spacecraft was spin-stabilised at 100 rpm around the main axis aligned almost parallel to the Earth's axis with spin regulated by two small hydrazine thrusters. Spin access control and east-west station-keeping was provided by two pairs of large thrusters. Attitude information was provided by Earth horizon and Sun-lit sensors. A radiating dipole antenna directed S-band (333 kbs) transmission of DCP image data to the Data Acquisition, Telemetry, and Tracking Station at Odenwald, Germany for relay to the Meteosat Ground Computer System and Meteosat Operations Control centre at ESA's European Space Operations Centre (ESOC). The Meteosats carried a single imaging radiometer in visible/infrared wavelengths in addition to the Data Collection Platform.
