Future space ecosystems: on-orbit operations, preparation of orbital demonstration mission

R&I on phase B2-C mission study[[according to ECSS-M-ST-10C]] and target-oriented technology maturation (TRL 6) to prepare a low cost orbital demonstration mission integrating robotic and autonomy technologies and technical building blocks with high-impact on future commercial services applying and enhancing the European Operations Framework for OOS. Technology maturation should aim at risk reduction of the intended pioneering orbital demonstration mission as well as at raise of confidence on OOS applications in general. The designed satellite platform should be compatible with a functional upgrade later in Phase D enabled by functional satellite modules (Orbital Replaceable Units to deliver new/enhanced functionality), developed outside this topic and able to be connected to the platform using a pre-existing standard interface[[Multi-functional interface for OOS applications providing at least transfer of mechanical loads, power and data (e.g. HOTDOCK, iSSI
