To solve the cumbersome and complex problem of parameter tuning of the GPS tracking loop,and the time-consuming problem of repeated compilation of FPGA,a kind of Hardware-in-the-Loop system of GPS receiver baseband processing unit based on FPGA is designed.The system used the GPS baseband processing unit designed by FPGA as the core to complete the acquisi-tion of the satellite signal and baseband signal processing.The processing results are transmitted to tracking loop designed by the Simulink in real time through the Ethernet.After processing,the results are fed back to the baseband processing unit to complete the acquisition and tracking of the satellite signal.By test,the system realizes the acquisition and tracking of the satellite signal,the validity and accuracy of the platform are verified,and the efficiency of the design,tuning,verification and implementation of the GPS tracking loop is improved.It is useful for rapid development of GNSS IC and system.
