Goal of GMES
GMES aims at developing operational services,
following the example of meteorology but for
other domains such as emergency risk
management, air quality monitoring, land
monitoring, ocean / sea ice monitoring,
etc. Science needed to create and continuously
improve operational services
3
GMES Some key milestones
Initiation of GMES, Baveno Manifesto Gothenburg
EU Summit establish by 2008 an operational
European capacity for GMES Investments by ESA
and EC on services EU initiates Fast-track
services GMES becomes flagship ESA C-MIN in
Berlin funds Phase-1 of GSC programme ESA
Phase-2 approved EC-ESA agreement on GMES
signed EC Fast-Track services to become
operational ESA C-MIN in November - GSC Segment-2
adopted Launch of first GMES Sentinels

GMES components
  • Services Component
  • Produces information services in response to
    European policy priorities in environment and
    security
  • Relies on data from in-situ and space component
  • In-situ component
  • Mostly of national responsibility, with
    coordination at European level (EEA)
  • Space Component
  • EO missions developed specifically for GMES
    (Sentinels)
  • EO missions built for purposes other than GMES
    but offering part of their capacity to GMES
    (EU/ESA MSs, EUMETSAT, commercial, international)

Role of ESA in GMES Space Council Resolution
  • Development and procurement Agency for dedicated
    space infrastructure
  • ? Development of first spacecraft and Ground
    Segment, procurement of recurrent elements
  • Coordinator of the overall GMES Space Component
  • ? Definition of overall GSC architecture and
    plan for future evolutions, organisation of the
    access to GMES Contributing Missions and
    operation of Sentinels
  • ESA is expected to act as interim operator of
    Sentinel-1, -2 and Sentinel-3 (land)
  • EUMETSAT is the proposed operator of Sentinel-3
    (Marine), Sentinel-4 and -5
