AAC Clyde Space expects contract exceeding EUR 70 M for EPS-Sterna satellite radiometers

Work on the programme is expected to begin once the industrial contract has been signed. Revenue from the project will be recognised progressively as work is performed over the duration of the programme.

The microwave radiometer is the core weather instrument onboard each EPS-Sterna satellite and will be developed and manufactured by AAC Omnisys, the Gothenburg-based subsidiary of AAC Clyde Space. The instrument builds on technology demonstrated in orbit through the Arctic Weather Satellite mission.

"This programme represents an important step in Europe's next generation of weather monitoring capabilities and confirms the strong position of our microwave instrument technology in advanced atmospheric sounding missions," says Luis Gomes, CEO of AAC Clyde Space.

Further information about project execution, delivery schedule and financial effects will be communicated once the industrial contract has been signed.

About the EPS-Sterna programme
EPS-Sterna is Europe's next-generation operational weather satellite system providing frequent atmospheric temperature and humidity sounding data for numerical weather prediction. The constellation will consist of six satellites operating simultaneously in polar orbit, with replacement satellites launched over time to maintain continuous observations. The first satellite is expected to launch in 2029. In total, 20 satellites will be deployed during the programme's operational lifetime, which extends to 2042. The mission builds on technology demonstrated by the Arctic Weather Satellite mission. 

The EPS-Sterna satellites are built by OHB Sweden as prime contractor under a programme led by the European Space Agency (ESA) on behalf of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).

About the microwave radiometer
The microwave radiometer is developed and manufactured by AAC Omnisys, a subsidiary of AAC Clyde Space based in Gothenburg, Sweden. It combines high sensitivity with a compact design, making it possible to deploy advanced weather sensing capabilities on smaller and more cost-efficient satellites. The instrument includes multiple microwave channels, including the 325 GHz band, enabling observations of atmospheric moisture and ice formation inside clouds that are difficult to capture with other satellite instruments. These observations are essential for improving weather forecasts and monitoring the development of severe weather systems.
