Design of Micro Inertial Navigation Computer and Data Real-Time Displaying System Based on FPGA

Abstract

To meet the demands of high precision and real-time navigation calculating of some tiny volume projectiles in engineering, a kind of FPGA + DSP architecture hardware calculating system is designed. It transmits motion and attitude information through the wireless transmission and displays the messages on upper computer. In the system, FPGA is the kernel controller, which is used to control all timing logic, start the DSP calculating and transmit the wireless data of navigation information and data acquisition of micro inertial measurement unit (MIMU). DSP as a processor for navigation algorithm, calculates the navigation parameters and transmits the result to FPGA. This design system has the characteristics of low power consumption, small volume and high flexibility. It can collect MIMU data, transmit wireless data and display navigation information on upper computer. The experiment proved that the method is feasible
