Analysed the requirement of the navigation computer for the small integrated navigation system

the target of hardware design is decided.The embed navigation computer used TMS320C6713 digital signal processor（DSP） as the core processor

the 18-bit differential analog-to-digital convert circuitry

the 16-bit digital-to-analog convert circuitry and other interface unit are designed.The navigation computer uses the field programmable logic technique to simplify the circuit design.The navigation software designed in DSP platform which ensure the integrated navigation system employs the DSP navigation computer instead of the personal computer.The experiments show the integrate navigation system based on DSP meets the design requirement with enough precision high speed

portable and low-cost

which is significant to the miniaturization of the navigation system.
