    Ground Segment overview

    ESA-ESRIN

    The GMES Ground Segment provides access to Sentinel data. It also interfaces with the Contributing Missions to achieve a coordinated data stream, satisfying the observational requirements for GMES services.

    The Ground Segment also comprises the mission control to operate the Sentinel satellites and the facilities to handle the data received from the Sentinels and elaborate the data into products for GMES Services.

    The Ground Segment, which is spread geographically, relies on existing national public and private facilities and infrastructure coherently managed.

    The Coordinated Data Access System will make datasets available. The datasets are defined by the GMES Service Project requirements after analysis of the Contributing Missions capacity.

    The Data Access Portfolio document defines all these datasets and also identifies the data access conditions, such as ordering mechanisms, processing level, delivery timeliness, data licensing, under which these data are made accessible to the eligible services.

    The dedicated GMES Space Component Data Access website has been set up for GMES Services to access Earth observation data.
