5 4 April 2014 Sentinel-1A offers the world the first ever EO selfie

6 4 April 2014 All Deployments Successfully Completed at L+10h 45

7 LEOP Completed in three days as planned All s/s were switched on First X-band downlink in Matera (I) First SAR acquisition occurred on 6 April at L+62h33 (WM over Svalbard)

8 Sentinel 1: C-band SAR mission! Data continuity of ERS and ENVISAT missions! Copernicus radar imaging mission for ocean, land, emergency! Applications: monitoring sea ice zones and the arctic environment surveillance of marine environment (e.g. oil spill monitoring) maritime security (e.g. ship detection) wind, wave, current monitoring monitoring of land surface motion (subsidence, landslide, tectonics, volcanoes, etc.) support to emergency / risk management (e.g. flooding, etc.) and humanitarian aid in crisis situations mapping of land surfaces: forest, water and soil, agriculture, etc.

9 Sentinel-1 C-band SAR mission Mission profile:! C-Band SAR at 5.4 GHz, multi-polarisation! Sun synchronous orbit at 693 km mean altitude! 250 km swath width (Interferometric Wideswath mode)! 6 days repeat cycle at Equator with 2 satellites! 7 years design life time, consumables for 12 years! 4 nominal mutually exclusive operation modes

13 Sentinel-1: un-precedent data volume With the Sentinel-1 instrument characteristics and mission operations concept, data volume handling is a major challenge both for Ground Segment operations and also for user data access and management Systematic generation of Level-0 products: about 1.5 TB per day (both satellites) to be generated, real time quality checked and archived Systematic processing to Level-1 products: about 1.7 TB per day (both satellites) to be generated, real time quality checked and archived To be disseminated to users with an on-line data access X&band(raw(data( 150 Mbps(average(sustained(rate( Sen$nel&1(Core(opera$onal(user(Products( 300 Mbps(average(sustained(rate( Sen$nel&1(Core(PDGS( ingestion, data circulation, L0 processing, L1/2 processing, radio/geo calibration, QC, archiving

14 Sentinel 1 mission status! Sentinel-1A launched on 3 April 2014 on Soyuz from Kourou! Nominal orbit reached on 7 August 2014! Sentinel-1A commissioning phased completed on 23 September 2014! Sentinel-1A Operational Qualification phase on-going (see next slide)! Data flow opened to all users on 3rd October 2014! Satellite and ground segment status and performance are nominal! Sentinel-1B satellite under procurement, launched foreseen in early 2016

15 Why Sentinel-1 is a special mission? An operational qualification phase leading to the Routine Operations The Sentinel-1 full mission exploitation capability is based on the routine operation of the 2-satellites constellation. Mission exploitation capacity is gradually achieved from Sentinel-1A launch to routine operations before the Sentinel-1B launch.

26 SENTINEL-1, A NEW ASSET TO RESPOND TO EMERGENCY ACTIVATIONS

27 Sentinel-1 vs ENVISAT ASAR over Namibia ENVISAR ASAR APP

28 Pauline Mufeti, Head of Namibia s National Hydrological Services, said: "Currently, it s practically impossible to monitor the situation from the ground because accessibility is difficult and virtually impossible during the rainy season "During this last flood, we could not determine where the water inundating villages was coming from. "The flooding in the Zambezi disrupts the livelihoods of the people and increases the risk of waterborne diseases. "Despite the bad weather and cloudy conditions we had been experiencing, Sentinel-1A could clearly depict the Zambezi flood plains from space
