1. A wireless signal receiving device, comprising:
a first antenna, for receiving a first wireless signal in a Global Positioning System (GPS) L1 band;
a second antenna, for receiving a second wireless signal in a GPS L5 band;
a third antenna, for receiving an external antenna wireless signal including the GPS L1 band and the GPS L5 band;
a first signal splitting device, coupled to the third antenna, for splitting the external antenna wireless signal into a third wireless signal in the GPS L1 band and a fourth wireless signal in the GPS L5 band;
a first signal switching device, coupled to the first antenna, coupled to the first signal splitting device, for individually switching and outputting the first wireless signal and the third wireless signal;
a second signal switching device, coupled to the second antenna, coupled to the first signal splitting device, for individually switching and outputting the second wireless signal and the fourth wireless signal;
a first module switching device, coupled to the first signal switching device, for switching an output route of the first wireless signal or the third wireless signal;
a second module switching device, coupled to the second signal switching device, for switching an output route of the second wireless signal or the fourth wireless signal; and
a first signal combination device, coupled to the first module switching device and the second module switching device, for combining wireless signals received from the first module switching device and the second module switching device into a fifth wireless signal.
