Abstract
For the problem that the calculation in aircraft routine planning system is huge, and time-consuming, and associating with the GPU (Graphics Processing Units) large-scale parallel computing feature, a fast calculation method for trajectory base on GPU is raised here. This method uses the Fourth-order Runge-Kutta to resolve the trajectory differential equations, makes the trajectory computing task
the control ability in CPU + GPU heterogeneous platform in data stream , Lastly, compute thousands of trajectories in the parallel mode. The experimental results show that the calculation accuracy of the method can meet the requirements, and the speed of the method is several decades faster than the traditional method computing on the CPU. This method is also offering some new ideas for the other related applications which have large-scale parallel calculation in aircraft route planning system.关键词
