Observing Systems Capability Analysis and Review Tool
Satellite Programme: Meteosat Third Generation (MTG) - “I” imaging, “S” sounding
Series of six operational meteorological satellites in geostationary orbit.
Follow-on of the MSG series. Main developments: 3-axis stabilisation, improved imager, lighting mapping, hyperspectral sounder, chemistry mission.
Imager and lighting mapper on units “I”.
Sounding and chemistry on units “S”.
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 design life time of the satellites is 8 years.
Nominal position: 0°.
The replacement policy is based on hot standby for imaging satellites (“I”), no redundancy for sounding satellites (“S”).
See detailed description at
PGS (Primary Ground Station) to acquire all data, pre-process and re-broadcast within tenths of minutes.
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).
EUMETCast [not exclusive of MTG], to disseminate all sort of satellite data by commercial satellites.
