OHB Sweden to build Sterna weather constellation

Thanks to the success of the Arctic Weather Satellite prototype and Eumetsat’s recent greenlight to develop a full constellation of similar satellites called Sterna, the European Space Agency has awarded OHB Sweden with the contract to build 20 satellites.

This marks a major step toward better monitoring rapidly evolving weather, improving forecasts of severe events in vulnerable regions such as the Mediterranean, and closing critical data gaps over the Arctic – the fastest-warming region on Earth and a key driver of Europe’s weather systems.
