Abstract:

This paper establishes a laser irradiation three-dimensional orbit dynamic model based on the theory of orbital mechanics and the interaction effects between laser and matters. With the position vector and velocity vector regarded as the initial data, and setting the parameters of laser, this model calculates the velocity and provides the real-time updates, which can actually reflect the process of the debris removal. It contains the ground-based and space-based models, both of them can output the orbit information of the debris real-time updates, and the graphical output directly displays the process of the orbital transfer. The effect of the velocity increment component on the orbit inclination is taken into consideration, thus this model can deal with the situation of the debris escape. Moreover, we successfully calculate the removal process and the result of various debris using ground-/space-based model. We suppose that it is the most difficult to remove steel, while multilayered insulation removal is the most efficient.
