Satellite Programme: Meteosat First Generation
Series of seven operational meteorological satellites in geostationary orbit, articulated in three steps:
the Meteosat Pre-operational series (Meteosat 1 to 3)
the Meteosat Operational Programme (MOP) (Meteosat 4 to 6), with minor improvements, mainly at system level (satellite architecture and in-orbit redundancy)
the Meteosat Transition Programme (MTP) (Meteosat-7), to bridge MOP to the Meteosat Second Generation (MSG).
European programme: ESA responsible of the development of the space segment and, in the Pre-operational phase, of the operations; EUMETSAT, starting with MOP, 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 (3 years in the Pre-operational phase).
The replacement policy, starting with MOP, is based on one operational satellite at 0° longitude and a hot standby in a close position.
Possible spare satellites are used for contingency purposes (Atlantic Data Coverage or Indian Ocean Data Coverage).
See detailed description at
PGS (Primary Ground Station) to acquire all data, pre-process and re-broadcast within tenths of minutes.
HRIDS (High Resolution Image Dissemination Service) for full-resolution image dissemination in near-real time.
WEFAX (Weather Facsimile) for broadcasting of image frames.
DCS (Data Collection System) to relay messages from self-timed Data Collection Platforms (DCP).
MDD (Meteorological Data Distribution), starting with MOP, to relay processed data generated at European meteorological centres (up to four).
