The European Union’s and the European Space Agency – ESA‘s Copernicus Radar Observing System for Europe at L-band (ROSE-L) is a satellite carrying the largest-ever L-band SAR radar planar antenna. Built by more than 15 ESA member states, the mission aims to monitor geohazards, track land use, agriculture and forestry, provide high-resolution soil moisture data and observe the Arctic and cryosphere. It will contribute to atmospheric, oceanic and land measurements, helping scientists analyze land cover, ocean surface currents, soil moisture, snow depth, vegetation and even crustal motion. ROSE-L is going to be a true European engineering marvel, integrating advanced technology to provide all these essential services with unmatched precision and reliability. The prime contractor for European Space Agency (ESA) is Thales Alenia Space Italia with responsibility for satellite and platform development, system integration and verification, as well as support for launch and commissioning.
With the delivery of the lower assembly and the upper cone of the second model to SAB Aerospace (CZ) in Brno, INVENT GmbH has successfully completed its contribution to the primary structure of the satellite. Together with the previously delivered upper assembly, they form the satellite’s backbone structure – an approximately 4-m-high tubular CFRP structure that combines minimum mass with the ability to withstand extreme launch loads and the harsh conditions of space.
Although this part of our contribution to the project has almost come to an end, we continue to follow its further progress with great interest and take pride in the satellite’s upcoming operation. We are grateful for the enjoyable and professional cooperation and look forward to continuing our collaboration with SAB Aerospace in future projects.
Further, we are continuing our work on the panels for ROSE-L’s impressive SAR antenna.
