Abstract
This paper presents the implementation-tation of the real-time software GPS Receiver based on FFT and FLL assisted PLL tracking algorithm. The FFT(fast fourier transform) based GPS si-gnal acquisition scheme provides a fast TTFF(time to first fix) performance. The tracking based on FLL assisted PLL enables tracking of GPS signal in a high dynamic environment. The designed software GPS receiver uses the indexing method for generating replica carrier to reduce computation load. The performance of the implemented GPS receiver is evaluated using high-dynamic simulated data from a simulator and real static data.
