Design and Implementation of the Tightly-coupled SINS / GPS Integrated Navigation System Based on FPGA for Target Missile

摘要：

　　A novel architecture of tightly-coupled SINS/GPS integrated navigation system based on FPGA for target missile is proposed in this paper.The whole system is built on a single single FPGA chip containing a Nios Ⅱ soft-core processor.In addition,the embedded real-time operating system μC/OS-Ⅱ is transplanted to the Nios Ⅱ processor for managing each module in the system.The system can still provide the high-precision navigation data to integrated control computer of target missile when the number of available satellites is less than 4 by means of processing the pseudorange and pseudorange rate seprately.Therefore,the system has the strong application significance in terms of reducing the route shortcut of target missile.
