Observing Systems Capability Analysis and Review Tool
Satellite Programme: Meteosat Second Generation (MSG)
Series of four operational meteorological satellites in geostationary orbit.
Follow-on of the Meteosat Operational Programme (MOP). Main improvements: more performing imager and introduction of radiation budget observation.
European programme: ESA responsible of the development of the space segment, EUMETSAT responsible of the mission requirements definition, the development of the ground segment and the full system operation.
The platform is inertially stabilised by spin.
The design life time of the satellites is 5 years.
The replacement policy is based on one operational satellite at 0° longitude and a hot standby in a close position, possibly used for, e.g., very frequent images of limited areas.
Possible spare satellites may be used for contingency purposes.
See detailed description at
PGS (Primary Ground Station) to acquire all data, pre-process and re-broadcast within tenths of minutes.
HRIT (High Rate Information Transmission) for full-resolution image dissemination in near-real time.
LRIT (Low Rate Information Transmission) for broadcasting of image frames and other data.
DCS (Data Collection System) to relay messages from self-timed Data Collection Platforms (DCP) to the PGS by a dedicated link.
GEOS&R (Geostationary Search & Rescue) to relay emergency signals to Local User Terminals (LUT).
MDD (Meteorological Data Distribution) to relay processed data generated at European meteorological centres (up to four).
EUMETCast [not exclusive of MSG], to disseminate all sort of satellite data by commercial satellites.
