Copernicus Sentinel-1 is a radar imaging satellite mission developed by the European Space Agency (ESA) as part of the Copernicus Programme. The mission is designed to provide continuous all-weather, day-and-night radar imaging for land and ocean services. The Sentinel-1 constellation consists of two identical satellites, Sentinel-1A and Sentinel-1B, launched in 2014 and 2016, respectively. Each satellite carries a C-band synthetic aperture radar (SAR) instrument, which can capture high-resolution images of Earth's surface.

The primary objectives of the Sentinel-1 mission include monitoring sea ice, oil spills, marine winds, waves, and currents, as well as providing data for land applications such as forest, water, and soil monitoring, as well as mapping of risk areas like floods and landslides. The mission also supports emergency response services, providing timely information during natural disasters and humanitarian crises.

The Sentinel-1 satellites operate in a sun-synchronous orbit at an altitude of approximately 693 kilometers, with a revisit time of six days for the same area. The data collected by the mission is freely available to users worldwide, promoting the development of various applications in environmental monitoring, climate research, and disaster management. The mission has significantly contributed to the understanding of Earth's dynamic processes and has become an essential component of the Copernicus Programme's Earth observation capabilities.
