MOP 2

NSSDCA/COSPAR ID: 1991-015B

Description

The Meteosat Operational Programme (MOP-2) satellite was the second operational geostationary Meteosat satellite following 3 pre-operational Meteosat satellites (Meteosat-1,-2,-3/P2). The primary goals of the MOP satellites were (1) to provide visible and IR day/night cloudcover data and radiances and (2) to disseminate image data to users through the Data Collection Platform (DCP). MOP-2 (or Meteosat 5) was a 2.1 m diameter, 3.195 m high stepped cylindrical body with solar cells on six main body panels. The spacecraft was spin-stabilized 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 stationkeeping were 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 center at ESA's European Space Operations Center (ESOC). The MOP-2 carried a single imaging radiometer in visible/infrared wavelengths in addition to the Data Collection Platform.
