Abstract: A global positioning system (GPS) receiver based on peripheral component interconnect (PCI) bus is reported. The navigation information is obtained by central processing unit (CPU) of personal computer (PC) controlling the correlator chips. Comparison of the synchronous measurement result of this receiver with that of a reference one shows the error trend is the same. The scatter plots of the horizontal error and vertical error distribution show that this measurement system is more stable and can reflect the position information exactly.

Key words: GPS receiver, PCI bus, hardware design, software design
