A signal processing module is provided to enable a user to confirm the current position quickly by integrating an antenna unit, arranged in the front end of a band processing chip, a clock generation unit, a signal processing unit and a GPS signal processing unit into one module. A signal processing module(100) comprises an antenna unit(101), a low noise amplifier(110), a filter unit(120), a signal processing unit(130), a clock generation unit(150) and a power supply unit(140). The signal processing module is connected to a baseband processing unit through a connector. The antenna unit receives a wireless signal transmitted from a GPS satellite. The low noise amplifier is connected to the antenna unit to suppress the noise components to the maximum and amplify the received wireless signal. The filter unit passes the GPS signals of only a GPS signal band in the wireless signal and blocks the rest signals.
