针对工程应用中微小体积的导航解算应用场合,设计了一种FPGA+DSP架构的硬件导航解算系统,并通过无线传输将载体的三维运动姿态信息显示到上位机上。该系统中,FPGA是核心控制器,用来控制MIMU数据采集、启动DSP解算和导航参数的无线传输;DSP作为导航解算处理器,完成了导航参数的解算和数据传输。本设计系统具有功耗低、体积小和灵活性高的特点,能够完成MIMU数据的采集解算、无线传输和上位机显示,试验证明该方案切实可行。

To meet the demands of navigation calculating of some tiny volume applications in engineering,a kind of FPGA ＋ DSP architecture hardware calculating system is designed. It transmits motion and attitude information through the wireless transmission and displays the message on upper computer. In the system,FPGA is the kernel controller,which is used to collect acquisition data of MIMU,start the DSP calculating and transmit the wireless data of navigation; DSP,as a navigation algorithm processor,calculates the navigation parameters and transmits the result to FPGA. This design system has the characteristics of low power consumption,small volume and high flexibility. It can collect MIMU data,transmit wireless data and display navigation information on upper computer. The experiment proved that the method is feasible.
