SENTINEL-1D is a European radar Earth observation satellite flying as part of the Copernicus Programme. Like its Sentinel-1 siblings, it carries a C-band synthetic aperture radar (SAR) that can image the Earth’s surface in all weather and lighting conditions. This capability makes it especially valuable for applications such as environmental monitoring, disaster management, maritime surveillance, and land-surface mapping. Operating from a sun-synchronous low Earth orbit, Sentinel-1D is designed to deliver timely, consistent, and high-resolution data to support a wide range of operational services, ensuring that decision makers have up-to-date information on changing conditions over land, sea, and ice.
