Sentinel-1A
Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel 1 satellite launched as part of the European Union's Copernicus programme. The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions. It will track many aspects of our environment, from detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used. Copernicus is the long-term European Union Earth observation and monitoring programme under the former name of GMES (Global Monitoring for Environment and Security) and established by a Regulation that entered into force in 2014. It is a user-driven programme under civil control, which will notably encompass the launch of six families of dedicated, EU-owned earth observation satellites and instruments - the so-called Sentinels - and the ramp-up of the 6 Copernicus Services in the fields of atmosphere-, marine- and land-monitoring, climate change, emergency management and security. Copernicus data and services are available on a full, open and free-of charge basis to users, including EU institutions, Member States' authorities, the private sector for the development of commercial downstream applications and services, international partners, the global scientific community, and interested citizens. ==Mission history==
