Future orbital factories will require standardized components to manufacture and assemble modular spacecraft. One of such components is a multifunctional interconnect which allows to connect different subsystems of a modular spacecraft mechanically and electrically. To select the most appropriate one for the envisioned demonstration scenario of the PERIOD project a benchmark was performed at DFKI on the three European state-of-the-art interconnects. The tests compared the electrical and mechanical capabilities of the interconnects and set a precedent on how to design and execute future benchmarks of multifunctional interconnects.
