All Four Sentinel-1 Satellites Are Now Live

Europe's Earth observation capabilities have just received a significant boost with the operational deployment of all four Sentinel-1 satellites, providing near-real-time radar imaging of the planet's surface with a revisit time of 12 days and a spatial resolution of up to 5 meters. This constellation now offers unparalleled coverage of the globe, enabling more accurate monitoring of land use, sea ice, and natural disasters. The satellites' advanced Synthetic Aperture Radar (SAR) technology ensures data collection regardless of weather conditions. AI-assisted, human-reviewed.
