| Abstract: | Based on the embedded MIMU/GPS tightly coupled integrated navigation system developed by southeast university,the paper realized the platform data control and transmission for DSP and FPGA.Navigation computer is made up of DSP,FPGA and two slices of MCU.DSP is for navigation calculation,and FPGA is responsible for the preparation of external data.Two MCUs are used to alleviate the control.One is only for GPS control and decoding,another is not only for transmission of GPS data,but also for the PC communicat... |
