Simulation and Analysis of GPS Software Receiver

This paper describes an approach of implementing software based GPS receiver acquisition and tracking for L1 C/A signal. In this paper, in the deep research GPS signal capture principle´s foundation, carried on the simulation using Matlab to the GPS signals capture process to realize and to analyze. The simulation result further confirmed this method´s accuracy and the feasibility, this to further studies under the true environment in the simulation platform the GPS signal, the improvement satellite receiving unit performance has the very vital practical significance.
