Paper Abstract

Software GPS receiver can provide full access to signal processing inside the receiver channels. Thus, it has become the key component when investigating and developing advanced GPS signal processing technique. Based on the theory of GPS software receiver, we first illustrate a summary of a GPS receiver's mechanism in this paper. Then we focus on the algorithm and its implementation for signal acquisition and tracking. Finally the results and their analysis from acquisition and tracking from simulated GPS L1 data are given. The results show that the scheme in this software receiver is efficient to acquire the GPS signal and can be used to fulfill the demodulation of the input signal.
