Abstract:

A satellite positioning system （SPS） signal real-time processing experimental platform is designed in the paper. The platform receives and transmitsSPS signals to a FPGA development board and a host computer, after converting them into digital IF signals by the RF circuit. The signals sent to the F  PGA development board arc used to develop a digital SPS receiver, and the signals sent to the host computer is used to develop a software SPS receiver.  The platform offers a fundamental SPS signal processing algorithm library and a fundamental soft-core library to efficiently support the software and hardware development of SPS receivers. The prototypes of the digital GPS receiver and the software SPS receiver have been developed based on the platform,   which has high compatibility and can be used to develop new generation SPS receivers with the corresponding RF circuits. Application shows that the dev elopment efficiency and quality will be remarkably en- hanced with its help.
