Multi-spectral Imager (MSI) |
Sentinel-2A is a European optical imaging satellite launched in 2015. It is the first Sentinel-2 satellite launched as part of the European Space Agency's Copernicus programme. The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands. It will perform terrestrial observations in support of services such as forest monitoring, land cover changes detection, and natural disaster management.[4]
