| Abstract: | This paper presents a new kind of navigation computer with the characteristics of small size, low power, low cost and high performance. This computer consist of DSP(Digital Signal Processing) and AVR single-chip processor, AVR single-chip processor has functions of data collected and I/O controlled etc; DSP is used to process the data. The AVR single-chip processor and DSP are designed on the same circuit diagram to realize the algorithm of integrated navigation system. |
