Rendez-vous and Docking (RVD) features and technologies are fundamental for unlocking key capabilities for spacecraft tasked with in-orbit operations. However, in a process that can be described as a “planned collision” between two bodies, safety is key, above all in a space environment were failures that may lead to damage to vehicles pose the greatest risks, and maintenance is, if not impossible, a great challenge at best. The case study that this thesis will focus on will be SROC (Space Rider Observer Cube), a future CubeSat based technological demonstrator mission, which aims at performing Proximity Operations and Docking with a larger mothercraft, Space Rider (SR), ESA’s new orbital platform.
