The European Copernicus Programme and Sentinel-1 and -2 Data Flow

Copernicus: A New Generation of Data Sources

Copernicus is a European space flagship programme led by the European Union

ESA coordinates the space component

Copernicus provides the necessary data for operational monitoring of the environment and for civil security

… and how the Sentinels contribute

Sentinel-1 Mission

• C-band SAR imaging mission in continuation of ERS and Envisat

• 7 years design life time with consumables for 12 years

• 12 days repeat cycle (1 satellite), 6 days for the 2 satellite constellation

• Up to 25 minutes duty cycle in any of the image modes

• 4 mutually exclusive SAR modes with different resolution and coverage

Main modes of operations: -IW over land and coastal waters (normally VV or VV/VH polarization)-EW over extended sea (VV or VV/VH) and sea-ice (HH or HH/HV) areas-WV over open oceans

Copernicus Sentinel Data Policy

Joint COM/ESA Sentinel Data Policy Principles have been prepared in 2009 - adopted by ESA MSs in Sep 2009

EU Delegated Act on Copernicus Data and Information Policy has been adopted in 2013 (C(2013)4311, final)

ESA got approval of updated Sentinel Data Policy from its Member States in Sep 2013. Main principles of Sentinel data policy:

Open access to Sentinel data by anybody and for any use

Free of charge data licenses

Restrictions possible due to technical limitations or security constraints
