In this paper, a delay/Doppler/propagation factor acquisition method for Global Positioning System (GPS) signal is proposed. Utilizing the Fast Fourier Transform (FFT) of the Auto-Correlation Function (ACF) for the received signal, together with some mathematical simplifications, a closed form solution is derived to estimate the delay/Doppler/propagation factor for the received signal. Unlike previous related estimation methods for this case, the proposed method has the advantage of not requiring any searching over the different parameters to perform the estimation.
