In the frame of the Global Monitoring for Environment and Security programme (GMES) jointly implemented by ESA and EC, ESA is developing the Sentinel-2 system, providing globally with systematic acquisition high resolution (10-20 m) optical observations with a high revisit tailored towards the needs of operational land services. This system will ensure data continuity of SPOT and Landsat satellite series and further enhancement to account of future service evolution..

Within the European Global Monitoring for Environment and Security (GMES) program, the Sentinel-2 mission will provide multi-spectral observations of the Earth surface. The Multi-Spectral Instrument (MSI) developed by Astrium, on board the Sentinel-2 satellite, includes a SWIR channel. Sofradir is in charge of the development, qualification and manufacturing of the infrared detector basis of this SWIR channel.
