Design a L1 Software GPS Receiver Based on IF GPS Signal Simulator

摘要

The conventional GPS receivers provide the least user flexibility. It is necessary to have software GPS receivers for easy implementation, simulation and analysis of algorithms. Additionally, a GPS software receiver is more flexible when it comes to adapting the entire receiver to work on the near future Galileo signals. In this software receiver design, the focus is on the baseband signal processing of L1 band C/A code GPS signal. The purpose of this paper is to develop the algorithms of baseband signal processing, including signal acquisition and tracking based on the IF GPS signal simulator.
