A deliverable of the Sentinels Rolling Archive, Operations Maintenance and Evolution contract, this document provides an annual look at the Sentinel Data Access Service operated by Serco, Gael, NOA and GRNET consortium for ESA in the Copernicus programme.

The current annual report is the third such report released by the data access service provider, Serco SpA, analysing the performance of the Data Access System and the public uptake of Copernicus Sentinel data.

This 2017 annual report takes up from where the 2016 report left off, and tracks the system’s performance and user activity during the period 1 December 2016 to 30 November 2017.
