Launched in the Autumn 2017 to foster the use of EO Data and to overcome technical problems related to downloading, storing, and processing Sentinel data, the RUS (Research and User Support)service supports and advises users of the European countries, willing to benefit from the Earth Observation program, Copernicus. Funded by the European Commission, managed by the European Space Agency (ESA), RUS is operated by CS GROUP (Payload data and application department) and its partners: Serco Italia S.p.A, Noveltis, Along-Track, and CS Romania.

It addresses, at no cost, users of the European countries wishing to take advantage from all the satellite data released every day by the Copernicus program.
