SENTINEL-6B is an advanced ocean altimetry satellite developed as part of the joint Jason Continuity of Service (Jason-CS) mission. It is designed to provide highly accurate measurements of sea surface height, which are crucial for monitoring ocean circulation, climate change, and weather forecasting. By carrying a suite of precise instruments—such as a radar altimeter, radiometers, and GPS receivers for exact orbit determination—Sentinel-6B contributes to long-term climate records, supports improved weather predictions, and enhances our understanding of global sea-level variations. As a collaborative effort among major space agencies and research institutions, this satellite plays an important role in ensuring the continuity and accuracy of oceanographic data worldwide.
