The first phase of the GMES Space Component covers the period 2006-2013. It focuses on the development of the first Sentinel-1 (all-weather day and night radar imager for land and ocean services), Sentinel-2 (high-resolution optical images for land services) and Sentinel-3 (instruments for ocean and global land monitoring services) satellites.
The second phase of the programme is now about to start and will run through until 2018. It will cover the development of the ground infrastructure, the completion of the Sentinel-1, -2 and -3 pairs and the development of the first two atmospheric payloads Sentinel -4 and -5 precursors.
