Creowave Filters Oy delivers radio frequency solutions to Europe’s new EPS-Sterna weather satellite system in collaboration with Sweden-based AAC Omnisys. The programme is an operational satellite programme led by EUMETSAT, based on technology validated in the European Space Agency’s Arctic Weather Satellite (AWS) mission and reflecting a modern New Space approach.
EPS-Sterna will form a multi-satellite constellation designed to provide continuous and accurate microwave-based weather observation data globally.
The RF solutions delivered by Creowave Filters are integrated into the satellites’ microwave radiometer systems, developed by AAC Omnisys, where signal processing quality is a key factor in measurement accuracy.
The solutions enable:
· highly precise and selective signal filtering
· resilience in electromagnetically demanding environments
· sustained performance over long operational lifetimes
Strong expertise in demanding RF applications
Creowave Filters is known for high-performance RF filters used in telecommunications networks and other high-reliability applications. The EPS-Sterna programme extends this expertise into space systems.
“The role of RF filters is particularly critical in systems where even minor disturbances directly impact data quality. In the EPS-Sterna programme, our solutions ensure signal purity and overall system performance,” says Esa Turunen, CEO of Creowave Filters.
“This marks a significant step for Creowave Filters as our technology is deployed in space as part of an operational satellite system,” Turunen says an adds:
“The seamless expert collaboration within the DA‑Group enabled the integration of Creowave Filters’ high‑performance solutions into the programme’s overall delivery. This reflects our strength as a reliable, single‑source partner capable of providing demanding and high‑performance system solutions all the way to satellite‑level applications,” says Sami Kotiniemi, CEO of DA‑Group.
Towards operational deployment
The EPS-Sterna satellite constellation will be deployed in phases and is expected to deliver long-term value for weather and environmental data services.
OHB Sweden serves as the prime contractor, with AAC Omnisys (part of AAC Clyde Space) supplying the microwave radiometers. The EPS-Sterna programme is fully funded by EUMETSAT and carried out under an ESA Contract.
Creowave Filters continues close cooperation with programme partners to ensure successful deliveries and the required system performance.
