| Abstract: | This paper presents a design and realization method of Strapdown Inertial Measurement Unit(SIMU) using open-loop fiber optic gyroscopes(FOG) and MEMS accelerometers.A high-speed digital signal processor(DSP) is used to carry out data acquisition,digital signal processing,and result output.The design of system hardware and software is presented in detail.The off-line calibration and on-line compensation have been done in the turntable test,and the result shows that the design requirement is achieved. |
