AAC Clyde Space Receives EUR 7.6 M Order for Power and Data Handling Systems for EPS-Sterna Satellites

AAC Clyde Space has received an order from OHB Sweden to deliver power and data handling systems for satellites within the EPS-Sterna programme. The order value is EUR 7.6 M (approx. SEK 81.9 M).

The order comprises Starbuck MINI Power Conditioning and Distribution Units (PCDU) and Sirius Data Handling Systems (DHS), supporting satellite power management and onboard data handling. The order includes 21 PCDU units and 21 DHS units, comprising 20 flight sets and one spare set for testing and verification purposes. Deliveries will take place from 2027 through 2029. As a significant portion of project activities takes place during the early phases, approx. 70% of the contract value is expected to be recognised by the end of 2027.

The systems build on AAC Clyde Space's flight-proven Starbuck and Sirius platforms, which were previously used in the Arctic Weather Satellite, the prototype mission for EPS-Sterna, Europe's next-generation weather satellite constellation.

“EPS-Sterna is a crucial programme for European weather forecasting, and we are extremely pleased to continue our close collaboration with OHB Sweden,” says Luis Gomes, CEO of AAC Clyde Space. “Our Starbuck and Sirius systems support the reliable operation of the satellites and build on proven performance in orbit.”

In March 2026, AAC Clyde Space also received an order from OHB Sweden to deliver microwave radiometers, the core weather instrument for the EPS-Sterna satellites.
