Flight Algorithms for Disaggregated Space Architectures (FADER) is an ERC-funded research aimed at contributing to the engineering and scientific knowledge of disaggregated spacecraft architectures. Particularly, it is focused on the relative dynamics of the modules of these systems. The long-term relative dynamics of fractionated architectures are different from those of traditional formation flying satellites. Although there are many works on relative dynamics and control of formation flying satellites, there are some open issues concerning the relative dynamics of disaggregated spacecraft and cluster flight. The main goal of this research is to find a cooperative guidance solution for autonomous disaggregated spacecraft enabling long-term cluster flight subject to orbit and attitude constraints.
