Abstract
This paper is a brief study of the global positioning system (GPS) P-code acquisition based on FFT. P-code has a higher chipping rate, better accuracy and anti-jamming property than C/A code. When C/A code is not available, direct P-code acquisition is useful. In this paper, the implementation on FPGA and DSP board proves that the technique using FFT (fast Fourier transform) has greatly reduced the acquisition times and calculations.
