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

Copernicus Sentinel Satellites
The Copernicus Services Component …
… 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
Sentinel- 2 Mission

Spatial Resolution
10m / 20m / 60m
Swath 290 km
Orbit Sun-synchronous at 786 km (14+3/10 revs per day), with LTDN 10:30 AM
Revisit Periodicity

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
