| Comments: | Platform Class: 65-Orbiting satellite Operations/Responsible organization: European Space Agency (ESA) Previous Name: N/A Launched Date: 25 April 2016 Commissioned Date: 16 September 2016 Operational lifespan till: ≥2023 (Minimum 7 years of mission life) Size: 2.8 m long, 2.5 m wide, 4 m high with 2×10 m-long solar arrays and a 12 m-long radar antenna Mass: 2300 kg (including 130 kg fuel) Instrument: C-band synthetic aperture radar (SAR) at 5.405 GHz NOTES: Sentinel-1 represents a series of satellites each carrying an advanced radar instrument to provide an all-weather, day-and-night supply of imagery of Earth’s surface. This C-band Synthetic Aperture Radar (SAR) builds on ESA’s and Canada’s heritage SAR systems on ERS-1, ERS-2, Envisat and Radarsat. Sentinel-1B is a European radar imaging satellite launched in April 2016. It is the second Sentinel-1 satellite launched as part of the European Union's Copernicus program. Sentinel-1B joins its identical twin, Sentinel-1A, in orbit to deliver information for numerous services, from monitoring ice in polar seas to tracking land subsidence, and for responding to disasters such as floods. Sentinel -1 imagery can be used to track many aspects of our environment, from estimating ocean surface wind speed, to detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in land use. The radar operates in two main modes: Interferometric Wide Swath and Extended Wide Swath. Interferometric Wide Swath mode, the default mode over land, has a swath width of 240 km and a ground sampling of 10 x 10 m . While the Extend Wide Swath mode has 25 x 25 m sampling with a swath with of 400 km.
