Abstract :
In view of the large and high real-time data transmission in the current strapdown INS, USB interface was integrated into the strapdown INS, and a strapdown inertial navigation real-time data processing system composed of the DSP, FPGA and the USB interface was designed. The system composition and working principle were described; the overall hardware design and software design of the system were introduced, where, the function characteristics and design method of the USB interface based on FT245 were focused on. The design of the system is concision and easy to realize, its cost is low and its size is small. Many experiments verified that the system can effectively accomplish the real-time solution and transmission of the flight posture and displacement information, especially useful for the some INS which requires high-speed data transmission.
