OHB-System produced the entire harness, which comprises eleven main elements, for the European space laboratory COLUMBUS within the International Space Station ISS. The Electrical Test Module (ETM) and the Flight Module (FM) harnesses were produced and tested in OHB-System's Columbus clean room. After testing, the ETM harness was integrated by OHB-System at Astrium. The FM harness was integrated in special jigs which were designed and built by OHB-System to exactly simulate the interfaces between the cable harness and the structural parts.

PICA (Pre-Integrated Columbus Assembly) is currently the largest harness project, allowing OHB-System to demonstrate its skills in this area.

Internal facilities:

OHB-System developed countless experiment facilities for the research laboratories on board the International Space Station ISS, including, for example, the European Physiology Module (EPM), a facility for conducting physiological experiments in space. It also worked on the biological laboratories Biolab and EMCS, the European Modular Cultivation System, and played a key role in the development of the Fluid Science Lab (FSL).

Similarly, parts of the European Drawer Rack, the universal experiment rack fitted to the COLUMBUS module, which feature OHB-System's video management unit to monitor on an ongoing basis the experiments integrated into it, were also built here.

OHB-System is the only space technology company which was materially involved in all of the research modules fitted to the COLUMBUS laboratory.
