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

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

The Design and Implementation of MSINS/GPS Navigation Computer

In order to meet the miniaturization, low power, low cost and increasingly high precision requires of Strapdown navigation system, the Strapdown Navigation Computer based on DSP and FPGA is researched in this paper. DSP is used to process the data. The FPGA has functions of data collected and I/O controlled etc, the dual-port RAM interface complete the data communication between DSP and FPGA. Two CPU give full play to their respective characteristics, the coordinated work, can complete the function of the navigation computer well.
