This paper focuses on the working principle, hardware and software of GPS receiver based on DSP TMS320C6713 chip of TI company. The process uses the DSP chip as the core, and complete the satellite signal's capturing, tracking and location analysis function, and try to output signal through the PCI bus connected to the computer directly, using the computer achieve signal monitoring and control on real-time. According to the design proposal, the receiver with good sensitivity and high precision and strong flexibility.
