摘　　要：在捷联惯性航向姿态测量系统中,微惯性器件是核心部分,陀螺和加速度计的精度直接影响整个系统的性能。本文设计了微惯性测量单元MIMU的结构,建立了数学模型,采用翻滚法和转台法,分别标定加速度计和陀螺的零位偏差、标度因子及安装角误差。The micro miniature inertial measurement unit(MIMU) are the important parts in the strap-down inertial heading and attitude system,the accuracy of gyroscope and accelerometer has affected the precision of whole system.The structure of MIMU was designed in this paper.Mathematical models of rolling method and rotating platform method were set up separately to calibrate zero bias,scale factor and installation angle error of accelerators and gyroscopes.
