| Abstract: | A method based on FFT for GPS signals tracking in the frequency domain is presented, that can be used in a static software GPS receiver. As the feature of a GPS data bit is 20 ms long and contains 20 C/A codes, block Addition acquisition method is used in tracking to reduce computational load and make preparations for tracking in real-time. |
