CopernicusSentinelsatellitter

Copernicus Sentinel-1 is a constellation of two radar imaging satellites, Sentinel-1A and Sentinel-1B, that form the European Space Agency's (ESA) flagship Earth observation mission. These satellites carry C-band synthetic aperture radar (SAR) instruments, allowing them to continuously image the Earth's surface regardless of weather conditions or time of day. This all-weather, day-and-night capability is a key advantage of the Sentinel-1 mission.

The Sentinel-1 constellation provides a wide range of applications. It is used for monitoring sea ice extent and thickness, detecting and tracking oil spills, and mapping land deformation due to earthquakes and volcanic activity. It also plays a crucial role in monitoring forests, managing agricultural land, and supporting disaster response efforts, such as flood mapping and damage assessment. The data collected by Sentinel-1 is freely and openly available to all users, fostering innovation and research across various scientific and operational domains. The mission's systematic data acquisition strategy ensures consistent coverage and allows for the detection of changes over time.
