Sentinel-2 is a family of Earth remote sensing satellites of the European Space Agency , created as part of the global environmental and safety monitoring project. Satellites are designed to monitor the use of land, vegetation, forest and water resources, and can also be used in the aftermath of natural disasters [1] .

The first satellite, Sentinel-2A , was launched on June 23, 2015 [2] . The launch of the second satellite, Sentinel-2B , was performed on March 7, 2017 [3] .
In January 2016, a contract was signed with Airbus Defense and Space for the creation of two more satellites, Sentinel-2C and Sentinel-2D , which will be launched after 2021 and will ensure continued operation of the program [4] [5] .
