Fast-Acquisition of GPS Signal Based on CUDA
Bo Zhang · Journal of Astronautics · 2010
To realize Fast-Acquisition of the C/A code on PC-Based software GPS receiver,a new method for Fast-Acquisition realized on Graphic Processing Unit ( GPU) is presented. Based on a FFT-based acquisition algorithm,this method uses GPU and Computer Unified Device Architecture ( CUDA) programming model to achieve a speedup over a standard CPU. Compared with the traditional acquisition method realized on standard CPU,the new method runs remarkably fast and the acquisition of 32 satellites under the cold-start condition takes only 1. 653 s,thus providing strong support for the real time processing on the PC based GPS software receiver.
