To avoid delays as a result of technology readiness issues, an important design requirement is to be independent of payloads and other new technologies flown. For convenient organization reasons, payloads are considered as separate subsystems, as can be seen in Fig. 3. This way, time tracking and control of the development of these payloads can be done at the highest level. Furthermore, to accelerate the whole design process from concept studies to verification and testing, both system and subsystems design are performed concurrently, with overlapping design phases as a result. The team, consisting of students with different but interdisciplinary backgrounds, is cooperating in a central office facing the in-house Clean Room facilities, improving communications and therewith easing design difficulties like decision making and interface control.
