Sentinel-1 is a space mission from ESA of the Copernicus Programme, consisting of a constellation of two satellites. The payload of Sentinel-1 is a Synthetic Aperture Radar in C-band which provides continuous imagery (day, night and all weather).
On 12 March 2010, the European Space Agency and Thales Alenia Space signed a contract worth €270 million to build the second satellite of the Sentinel-1 pair.
A summary of applications are:
- Monitoring sea ice zones and the Arctic environment, and surveillance of marine environment.
- Monitoring land surface motion risks
- Mapping of land surfaces: forest, water and soil
- Mapping in support of humanitarian aid in crisis situations
Shortly after the August 2014 South Napa Earthquake, data collected by Sentinel 1A was used to develop an interferometric synthetic aperture radar, or InSAR, image of the affected region. The Sentinel-1 satellites are expected to make analysis of earthquakes using InSAR techniques quicker and simpler.
Prime contractor of mission is Thales Alenia Space Italy. SAR instrument will be the responsibility of Astrium Gmbh. The Ground Segment prime contractor is Astrium with subcontractors Telespazio, WERUM, Advanced Computer Systems and ARESYS.
