Sentinel-1B is a satellite launched by the European Space Agency (ESA) on April 25, 2016. It is part of the Copernicus program, which aims to monitor the Earth's environment. Sentinel-1B works alongside its twin, Sentinel-1A, to provide high-resolution radar images of the Earth's surface, regardless of weather conditions or daylight. The satellite is equipped with a synthetic aperture radar (SAR) that can detect changes in land use, monitor natural disasters, and support humanitarian efforts. Its data is crucial for applications such as flood monitoring, land subsidence, and infrastructure management, contributing to better decision-making and resource management.
