Spread spectrum communication is rapidly developed in recent decades as a communications technology. Briefly introduced the GPS receiver software and the principles of the basic structure; capture loop is designed to track the GPS receiver design in one of the key technologies. This paper described the first spread-spectrum communications and tracking system to capture the basic principles; GPS signal tracking channel to capture the overall design scheme, introduced in the code tracking signal synchronized with the principle and implementation of carrier synchronization. IF GPS signals in the theoretical modeling and analysis, based on the use of Matlab / simulink for the capture of the GPS signal and tracking, in order to achieve on the intermediate frequency digital signal despreading process. A brief introduction of high dynamic GPS spread spectrum signal acquisition and tracking technology. Finally, FPGA-based simulation results and test data to verify.
