FPGA Inertial Navigation System Design and Realization

The design and completion of FPGA based on low cost strapdown inertial navigation system MEMS is presented.Navigation system takes FPGA as the main controller of real-time data acquisition and communication,NIOSII soft core processor for navigation calculation and data fusion algorithm.The overall system architecture and the six position method and experimental inertia device for compensation algorithm are discribed.Through the six position method and experimental testing,the prototype measured data and the result are verified after compensation,inertial navigation system,device error compensation scheme feasibility.
