The Sentinel-3B satellite scheduled for launch this spring, will be flying 30 seconds apart from its twin, Sentinel-3A, during the commissioning phase. This temporary tandem arrangement is to obtain better cross-calibration between instruments, thus reducing uncertainties in the multi-satellite time series and ensuring an overall high data quality.

The Copernicus Sentinel-3A satellite has been delivering data since its launch in early 2016. Its measurements have shown an excellent quality from the start, confirming its high degree of usefulness for the mission's current applications as well as potential future ones.

Carrying a suite of state-of-the-art instruments, it provides systematic measurements of Earth's oceans, land, ice and atmosphere to monitor and understand large-scale global dynamics and provide critical information for ocean and weather forecasting.
