5. 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

9. 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
