Programme details
Programme description
Two-satellite programme for ocean and land observation, to provide continuity to the Envisat MERIS, RA-2 and AATSR.
ESA programme co-sponsored by the European Commission in the context of the Copernicus programme (formerly: GMES, Global Monitoring for Environment and Security). ESA responsible of development and early operations, EUMETSAT responsible of routine operations.
The platforms are actively stabilised over 3 axes.
The design life time is 7.5 years.
The satellites are launched at a short time interval in order to fly in constellation for larger combined swath and redundancy. Sunsynchronous orbit around 10:00. 180° dephasing between the two satellites.
See detailed description at

Data circulation
The global data are stored onboard and downlinked to the Svalbard station.
Real-time data can be received at appointed stations.
Data are processed at the Payload Data Ground Segment (PDGS), a distributed system common to other Sentinel satellites of the GMES framework.
Specific products for Marine use are processed by EUMETSAT.
