Sentinel-2B is a European optical imaging satellite that was launched on 7 March 2017. It is the second Sentinel-2 satellite launched as part of the European Space Agency's Copernicus Programme, and with its orbit phased 180° against its sister satellite, Sentinel-2A. The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands. It provides information for agriculture and forestry, among other services, allowing for prediction of crop yields.^[4]
