Abstract: In order to analyze the procedures from both debris and removal system perspectives during debris deorbiting to improve the removal planning and schemes, a three dimensional simulation platform for orbital debris removal with spacebased laser system was constructed based on the trackable debris data. First of all, requirements, overall structures and modules of the simulation platform were fully described. Then laserdriven orbital transfer model was analyzed to realize the modules. Finally, the simulation platform was developed using C++/Qt and validated by simulations. This simulation platform can be used to removal planning for various spacebased lasers and debris, removal system design for hotspot debris removal and spacecraft defense as well as scheme optimization for clean space.

Key words: active debris removal, spacebased laser system, 3D simulation;orbital transfer, removal planning
