Observing Systems Capability Analysis and Review Tool
Satellite Programme: EUMETSAT Polar System
Series of three operational meteorological satellites, named MetOp, in sunsynchronous orbit.
European programme: ESA responsible of the development of the space segment, EUMETSAT responsible of mission requirements definition, development of the ground segment and full system operation.
The platforms are actively stabilised over 3 axes.
The design life time of the satellites was extended from 5 years to 6 years.
The replacement policy is based on launching satellites in sequence, roughly 6 months before the expected end-of-life of a satellite.
The satellites exploit sunsynchronous orbits at 09:30.

CDA (Command & Data Acquisition station) to acquire the stored Global Data Stream (GDS) that collects all instrument data.
ADA (Antarctic Data Acquisition) additional station to acquire stored GDS at an opposite latitude to the CDA in order to reduce on-board data storage and improve timeliness.
AHRPT (Advanced High Resolution Picture Transmission) for real-time broadcasting of all instrument data in digital form.
LRPT (Low Resolution Picture Transmission) for real-time broadcasting of selected data.
A-DCS (Advanced Data Collection Service, also called Argos-3) to localise DCP (Data Collection Platform) and relay their messages, with possibility of sending commands to the DCP.
S&RSAT (Search & Rescue Satellite-Aided Tracking System) to relay emergency signals to Local User Terminals (LUT).
EUMETCast [not exclusively dedicated to EPS] multi-mission DVB retransmission service by telecommunication satellite.
EARS (EUMETSAT Advanced Retransmission Service) [not exclusively dedicated to EPS] acquisition of regional data by a network of direct read-out stations, for near-real time retransmission by various means.
EUMETSAT Data Centre in Darmstadt for differed-time data and products.
