“…Furthermore, a debris object or a satellite in safe mode after a malfunction will not be in a stable attitude but will be tumbling, which makes the difficult task of characterizing its motion, identifying suitable capture features, approaching it, grasping it, stabilizing it and finally executing servicing operations a daunting challenge. Therefore, on-orbit servicing and active debris removal require substantial advances in the fields of sensing, relative navigation, path planning, controls, modeling of dynamic systems, robotics, communications and operations (Moosavian and Papadopoulos, 2007;Fong et al, 2013;Flores-Abbad et al, 2014;Shan et al, 2016;Wilde et al, 2019).…”
