Sentinel-2, which is the main source of EO data for the Sentinel-2 for Agriculture project, is one of the 5 missions that ESA is developing in the frame of Europe’s Copernicus programme.
This land monitoring mission consists of a pair of satellites, carrying each one an optical payload with visible, near infrared and shortwave infrared sensors, providing continuity for the former Spot and Landsat missions. Both sensors will include 13 spectral bands (4 bands at 10 m, 6 at 20 m and 3 at 60 m) with a 290 km swath, providing continuity for the current Spot and Landsat missions.
Sentinel-2, with its final two units in operation, will reach a revisit time of 5 days at the equator and 2–3 days at mid-latitudes. The first of them, Sentinel-2A, was launched on 23 June 2015, whereas Sentinel-2B was launch on 7 March 2017.
