Design of SINS/GPS Integrated Navigation System Based on DSP+FPGA

Because of the low cost and the miniaturization, the integrated navigation system become an important development trend of current inertial navigation system. In this paper the SINS/GPS integrated navigation system based on technology of DSP + FPGA was designed, which included the hardware circuit, using DSP + FPGA to replace the original working mode with microprocessor as the core processor. At the same time, the strap- down decoding algorithm was designed. The design implemented the function about the system communication, data acquisition and navigation data decoding, and was verified by the initial alignment test.
