HELSINKI — OHB Sweden has won a record contract for Sweden's space sector to build 20 satellites to boost Europe's weather forecasting and climate monitoring capabilities.

The contract, signed March 18 between the European Space Agency and OHB Sweden on behalf of EUMETSAT, covers the development and production of 20 small satellites for the EUMETSAT Polar System – Sterna (EPS-Sterna) program. Worth 248 million euros ($287 million), it is described as Sweden's largest satellite contract.
