Operational Research in Multi Space Debris Removal Using Space Maneuver Vehicle

This paper investigates the operational research in active debris removal and focuses on the orbit control in multi debris removal. Far-range trajectory is the crucial phase which guides chaser to proximity of target debris in sequence and provides precondition for further rendezvous control. Far-range trajectory can be divided into two modes depending on velocity requirement at the engagement instant. A novel mode, fly-by trajectory, is firstly proposed for far-range trajectory control corresponding to debris capture by compact with whipple material. Compared with general rendezvous and capture mode, there is no requirement on relative velocity in fly-by mode. At last, hybrid optimization algorithm is applied to far-range trajectory optimization based on multi-revolution Lambert algorithm. Simulations are conducted with three scenarios to illustrate effectiveness of proposed concept. This paper summarizes relevant work in this field and presents our new research in far-range orbit control.
