The embodiment of the invention provides a satellite signal receiving and processing system and a satellite signal receiving and processing method. The system comprises a filter, a first low noise amplifier, a mixer, a second low noise amplifier, a digital-to-analog converter and a visual signal processing module, wherein the visual signal processing module comprises a filtering sub-module, a signal synchronization sub-module, a baseband processing sub-module, a data analysis sub-module and a display sub-module. According to the satellite signal receiving and processing system and method provided by the embodiment of the invention, it is possible to synchronize the reception and processing of a satellite signal, thereby satisfying the real-time analysis requirement of a tester for the satellite signal, and since the processing result can be displayed directly in a visual manner, the tester can view the satellite signal processing result intuitively at the first time, thereby improvingthe user experience.
