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 Sentinel Data Policy = FREE and OPEN access Copernicus Sentinel Data Policy
