Design of Embedded GNSS Receiver Based on FPGA and DSP

Along with the deepening of GNSS receiver application,the performance requirements for power consumption and volume is higher and higher,the large-scale integrated circuit chips such as field-programmable gate arrays(FPGA) and high performance digital signal processor(DSP) are widely used in embedded GNSS receiver.A design of baseband signal processing of embedded receiver based on FPGA+DSP is introduced,and one of core design is the digital signal processing unit.FPGA is used to carry correlation.And DSP is designed to achieve processing satellite signal and the navigation data.System static test show that this receiver has characteristic of littler bulk,lower power and real-time.
