Sentinel-1 is a satellite mission developed by the European Space Agency (ESA) as part of the Copernicus program. It consists of two satellites, Sentinel-1A and Sentinel-1B, which use synthetic aperture radar to capture high-resolution images of the Earth's surface, regardless of weather conditions or daylight. The primary purpose of Sentinel-1 is to monitor land and sea changes, including natural disasters, urban development, and environmental changes. The data collected supports various applications, such as disaster management, agriculture, and climate change studies, providing valuable information for researchers and policymakers.
