Sentinel-6B Launch: A New Era for Measuring Sea Level from Space

Copernicus Sentinel-6B, scheduled for launch in November 2025, represents Europe’s next step in monitoring sea level from space. Building on the legacy of Sentinel-6A, it will extend the long-term record of ocean height observations, ensuring the continuity of high-precision satellite altimetry data feeding into Copernicus Marine’s ocean monitoring and forecasting products.
