Abstract： Satellite signal simulator for global navigation satellite system（GNSS） can evaluate the accuracy of capturing, tracing and positioning of GNSS receiver. It has significant use-value in the military and civil fields. The system adopts the overall design scheme of digital signal processor (DSP) and field-programmable gate array (FPGA). It consists of four modules: industrial control computer simulation software, mid-frequency signal generator, digital-to-analog (D/A) module and radio frequency (RF) module. In this paper, we test the dynamic performance of simulator using the dynamic scenes testing method, and the signal generated by the designed simulator is primarily validated.
Key words： global navigation satellite system（GNSS）; digital signal processor (DSP); field-programmable gate array（FPGA）; simulator
