AAC Clyde Space has received a €76.3 million order from OHB Sweden AB to deliver 20 microwave radiometers for the EPS-Sterna satellite programme. These instruments serve as the core weather payload for the constellation.
Work on the programme begins immediately. Revenue will be recognized using the percentage-of-completion method, with approximately half of the contract value expected to be recognized by the time the first six instruments are delivered at the end of 2028. The remaining instruments will follow at a rate of two per year until 2035.
The microwave radiometer, developed and built by AAC Clyde Space’s Gothenburg-based subsidiary AAC Omnisys, is mission-critical for each satellite. It measures atmospheric temperature and humidity—data essential for modern numerical weather prediction. The instrument’s technology has been validated through the Arctic Weather Satellite and enables a new generation of smaller, more capable, and cost-efficient weather satellites.
“We are extremely proud of this programme and thank OHB, ESA and EUMETSAT for entrusting us with the supply of the critical payload for this next generation weather mission,” said Luis Gomes, CEO of AAC Clyde Space. “These instruments will improve global weather forecasts, while significantly reducing the cost of weather missions. It is a perfect example of how we connect space technology with benefits that make a difference in our daily lives.”
The EPS-Sterna satellites are being 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).
“EPS-Sterna is an important programme for European weather forecasting, and a strong example of Swedish space capabilities,” said Fredrik Sjöberg, Managing Director of OHB Sweden. “Together with AAC Clyde Space we demonstrated this technology in record time and at significantly lower cost. We have a long history of collaboration and look forward to continuing this partnership.”
