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

Abstract:

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-IIis 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.
