Simulation and Analysis Acquisition of GPS C/A Code Signals in GPS System

Software-based GPS (SGR) Receiver can analyst processing the GPS signal at the lowest level of GPS raw signal data from the antenna. 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.
