Design / development of GPS receiver based on software, they are able to implement windows and C language on PC environments.Although It can successfully track the GPS signal, calculate the user position in real-time GPS calculation time, capture and track the signal isstill huge all software only GPS receiver. If the need for multipath mitigation, interference cancellation, and weak signal detection in supplementary signal processingis, FPGA / DSP based methods must provide additional computational power, which is a promising solution for advanced (Software Defined Radio (SDR)) SDR GPS receiver 1. In this paper, we propose a high-level design tool of software GPS receiving based on FPGA. We use a baseband signal processing design of GPS receiver based on Simulink and Xilinx system generator. This requires huge computation, such as signal processing components, correlation, C / a codegenerator, DCO (authentication code loop) designed by Xilinx FPGA block and implemented. The performance of the designed receiver is shown in thisreport. Xilinx launched system generation software, which can use MATLAB's Simulink to implement fpgadesign. In using this software, although we design Simulink module, without using FPGA programming knowledge.
