The Study On The Strapdown Navigation System And Hardware Design Based On FOG And DSP

The navigation, the aviation and the astronautics enterprise rapid development cannot leave the inertial navigation system, but strapdown navigation is used to leads the system. Because replaced the convention with mathematics platform to be used to leads in the system the physical platform. Has a series of merits, already substituted for the platform type in many aspects to be used to leads the system, was being used to leads the domain to become a popular development direction.In many situations, needs to be used to the strapdown navigation small leads system design to insert the type system .At present quite mature and already massively utilized was is used to based on the PC104 strapdown navigation leads the system .But PC104 is the ordinary processor, because of its hardware architecture limit, is not suitable for to make the massive real-time data signal processing, was precisely this article to is used to under such background based on the DSP Czechoslovakia association leads the system to conduct the research.In the last few years, the DSP technological development is rapid. Already applied to many domains .Its specific hardware architecture suits extremely in needs to make mass datas processing each algorithm ,has highly effective, is high speed, merit and so on high accuracy, is in the current many domains must make algorithm processing to insert the type system the first choice component. Moreover this article uses the TMS320VC33 chip also has the floating point calculation ability, this has provided the fine foundation for the Czechoslovakia association algorithm realization, this article take the TMS320VC33 chip as a core, designed and debugs the data reading, the memory hardware electric circuit and the correlation software and so on strapdown navigation algorithm transfer, the result quite is good.
