Method and system for predicting collision probability of space objects via graphics processing unit
Patent number: 9990766Abstract: Method and system for predicting collision probability of space objects are provided. Space objects are allocated according to a total number thereof for parallel computation in a GPU device. Initial orbit states of the space objects are generated by an initial-orbit-state generation kernel of the GPU device. Orbit propagation for each space object is performed based on the initial orbit state to predict a state of each space object by an orbit propagation kernel of the GPU device. The predicted states of the space objects are collected by a predicted-orbit-state collection kernel of the GPU device. A real-time visualization and rendering of the predicted space objects are performed in a form of point cloud during interactions between CPU threads and GPU kernels. A CPU host predicts a collision probability of any two space objects among the multitude of space objects, according to the interactions between the CPU threads and the GPU kernels.Type: GrantFiled: October 29, 2015Date of Patent: June 5, 2018Assignee: INTELLIGENT FUSION TECHNOLOGY, INCInventors: Bin Jia, Kui Liu, Genshe Chen, Khanh D.
