Slide 4 ESA UNCLASSIFIED – For Official Use 4 mutually exclusive SAR modes with different resolution and coverage Polarisation schemes for IW, EW & SM: single polarisation: HH or VV dual polarisation: HH+HV or VV+VH Wave mode: HH or VV SAR duty cycle per orbit: up to 25 min in any of the imaging modes up to 74 min in Wave mode Main modes of operations: -IW over land and coastal waters (normally VV or VVVH polarization) -EW over extended sea (VV or VVVH) and sea-ice (HH or HHHV) areas -WV over open oceans I. Sentinel-1 mission overview Sentinel-1 SAR imaging modes

5. ESA UNCLASSIFIED – For Official Use In line with the Sentinel operations strategy objectives:  Implement pre-defined and conflict-free observation plans, aiming at fulfilling,. to the best extent, the observation requirements from: - the Copernicus services - the use by ESA / EU Member States  In addition, on a best effort basis: -ensure continuity of ERS/ENVISAT -implement requirements from the science community -contribute to international cooperation activities. During the ramp-up phase: Start serving selected project needs located outside already established observation zones on a best effort basis  Need to find a priori the solutions for potential conflicts among users (e.g. different SAR operation modes / polarisation required over the same geographical area)  Build substantial archives - II.
