China Air Force Engineers propose space-based laser to remove small space junk

•, brian wang

The orbital momentum models of small scale space debris and space-based laser station were established. The velocity variation of the space debris ablating by the space-based laser station was analyzed, and the orbit maneuver of the space debris irradiated by laser station was modeled and studied. The variations of orbital parameters of the space debris orbit respectively without and with irradiation of high-power pulsed laser were simulated and analyzed, and the impacts of the inclination and right ascension of ascending node (RAAN) of the space-based laser station on debris removal were analyzed and discussed. The simulation results show that, debris removal is affected by inclination and RAAN, and laser station with the same inclination and RAAN as debris has the highest removal efficiency. It provides necessary theoretical basis for the deployment of space-based laser station and the further application of space debris removal by using space-based laser.
