Abstract

Software defined GPS receiver has been developing because it can be processed advanced signal algorithms and also developed for precise navigation. Signal processing modules such as signal acquisition, signal tracking and navigation demodulation are implemented in software to estimate the receiver position, velocity and time (PVT). Signal tracking is important task in order to estimate the receiver’s and satellites position by demodulating navigation bits which are obtained from this. In this paper, implementation and analysis of signal tracking loop is mainly described and there are two main tracking loop as carrier and code tracking loop on GPS L1 signal. Delay Locked Loop (DLL) is to track code delay or code phase of GPS Coarse or Acquisition (C/A) code while Phase Locked Loop (PLL) is used to track GPS L1 carrier frequency as well as Doppler Frequency Shift. The implementation of DLL and PLL, and analyses of parameters which effects on navigation bits is also briefly discussed. The results confirm the analysis of signal tracking loops for software defined GPS receiver based on the experimental studies. The real time applications for software defined GPS receiver are very important to implement the navigation system in future because of the effective analyses on theoretical consideration.
