GPS signal acquisition and processing are one of important technology for GPS software receiver. Usually, algorithms of GPS signal acquisition and tracking relied on GPS signals produced by simulator. Systems of GPS data acquisition based on FPGA and DSP are designed and real GPS signal can be acquired in this paper. Hardware and software of systems are analyzed detailedly. Further, the results of signal tracking using the observational data from processing systems are displayed in this paper. The relevant results show that systems of GPS data acquisition work well and lay the foundation of software receiver applied in the engineering fields.
