From the Heart of Europe into Space. Since 2018 OHB Czechspace, located in Brno, Czech Republic, has been a member of the Space and Technology group OHB SE, one of the space industry leaders in Europe. OHB Czechspace focuses on the development, design, verification, procurement, testing and related product assurance tasks of spacecraft and launcher structures for governmental space agencies as well as for other space industry players. Over the short history the company has been awarded multiple contracts within European Space Agency (ESA) programmes such as the planetary defence mission HERA, PLATO space exploration mission and the Copernicus Earth observation mission CO2M. In 2022, OHB Czechspace was awarded a contract by ESA for the Czech satellite mission SOVA to conduct the first phase of the Ambitious Project. SOVA will observe processes in the middle and upper atmosphere to improve climate and weather prediction models. The success of the company is driven by our team of highly skilled employees with passion for innovation and space, their commitment and quality of work performed.
