Even space debris smaller than 10 cm can cause fatal damage to satellites. The number of such “lethal
nontrackable” objects is estimated to be over a million. A laser-based active debris removal method can
solve this problem. In this study, we show that the error in orbit prediction can be at most 2 cm in 30
seconds. We also show that taking the Moon’s gravity into account to the trajectory calculation improves
the orbit prediction error about 20%. We also discuss the direction of the ablation recoil force. This direction
is shown to be critical to the success of debris removal.
