摘　　要：设计了一台低成本的微惯性测量组合标定系统。采用变几何桁架实现MIMU横滚角、俯仰角的变化 ,由平台的转动实现偏航角的改变 ,以模拟载体的运动。计算机通过A/D、D/A板对滚珠螺旋致动器等执行机构进行控制 ,并对MIMU的输出进行同步数据采集 ;应用GPS对MIMU的位置和姿态进行辅助测量 ,运用GENIE、MATLAB等设计了相应的软件 。A low cost calibration system for micro inertial measurement unit(MIMU)has been designed.It simulates the movement of carrier using variable-geometry truss to change the roll and pitch angule,to alter the yaw angule with turning platform.The mechanical elements such as ball screw actuators are controlled by computer with A/D and D/A boards which collect the MIMU output data synchronously.The position and attitude are accessorially measured by GPS receiver.The software is designed using GENIE and MATLAB to make arithmetic processing and graph display.
