Sentinel-2A, 2B – European Space Agency (ESA) project Sentinel is equipped with an optoelectronic multispectral sensor for surveys with a resolution from 10 to 60 m in the visible, near infrared (VNIR) and short-wave infrared (SWIR) spectral zones, including 13 spectral channels, which ensures the display of differences in the state of vegetation, including temporal changes, and minimizes the impact on the quality of the atmosphere. The orbit has an average altitude of 785 km, the presence of two satellites in the mission allows repeated surveys every 5 days at the equator and every 2-3 days at mid-latitudes.

The increased bandwidth of the survey, along with the high repeatability of surveys, allows you to track rapidly changing processes, such as changes of vegetation during the growing season. Sentinel-2 data provides GMES services related to land management, agricultural production and forestry, as well as monitoring of natural disasters and humanitarian operations. The uniqueness of the Sentinel-2 mission is due to the combination of large territorial coverage, frequent re-surveys and systematic obtaining of full coverage of the entire Earth by multispectral survey of medium resolution.
