| Abstract: | To implement the receiring of BeiDou (BD) satellite navigation signal, a navigation receiver system is designed based on ARM+FPGA. The SE4120 chip is used as the receiver’s radio frequency (RF) front-end. The AT91SAM9G20 chip based on ARM9 core and the Cyclone III series EP3C120F484 chip are used as the base-band processing part. And the receiver’s software design is explained, including the capture engine, tracking engine, demodulation messages, and position resolution. The proposed receiver can demodulate the BD signal. |
