TL;DR: The unique data availability performance of the Sentinel-1 routine operations makes the mission particularly suitable for emergency response support, marine surveillance, ice monitoring and interferometric applications such as detection of subsidence and landslides.

TL;DR: The Copernicus Sentinel-1 Earth Radar Observatory, a mission funded by the European Union and developed by ESA, is a constellation of two C-band radar satellites, which have been conceived to be a continuous and reliable source of SAR imagery for operational applications such as mapping of global landmasses, coastal zones and monitoring of shipping routes as mentioned in this paper.

TL;DR: In this article, the authors proposed a new operational mission concept for the GMES Sentinel-1 system to guarantee continuity of C-band SAR data and products availability to operational entities who exploit satellite radar imagery since ERS 1 operations.

TL;DR: The ESA Sentinels constitute the first series of operational satellites responding to the Earth observation needs of the EU-ESA Global Monitoring for Environment and Security (GMES) programme as mentioned in this paper.

TL;DR: In this paper, a trade-off between fast access/response to (or frequent revisit of) a few regions of interest and maximization of geographical coverage within the satellite orbit repeat cycle is defined.
