Yan Yue-peng · Transducer and Microsystem Technologies · 2011
The GPS receiver based on ARM and FPGA is designed for civilian and military application.The GP2015 chip is used as the receiver's RF front-end.The AT91SAM9261 chip based on ARM9 core and The Cyclone II seriers EP2C70F672I8 chip are used as the base-band processing part.Also the receiver's software design is explained,including the capture engine,tracking engine,demodulation messages,and position resolution.Through the field test,the receiver's positioning precision is 6m(longitude)/8m(latitude),and the dynamic performance is 2000m/s.The receiver can achieve high dynamic navigation and positioning.It has small size,low power consumption.
