摘　　要：捷联惯性测量系统是“动中通”系统(移动中的卫星地面站通信系统)的重要组成部分。捷联惯性测量系统能够实时测量车体的姿态和航向信息,使得“动中通”系统能够控制天线精准地指向卫星,实现车辆运动过程中的卫星通信。传统的车载捷联惯性测量系统内集成了三只激光陀螺仪,系统价格昂贵、体积较大。针对激光陀螺捷联惯性测量系统价格昂贵的问题,选用中等精度的光纤陀螺代替激光陀螺,开展了光纤陀螺惯性测量系统的设计,描述了系统组成、部件选型及设计、系统算法、结构设计、经济性等设计内容。所设计的车载经济型光纤陀螺捷联惯性测量系统较激光陀螺捷联惯性测量系统体积更小、硬件成本大幅降低。试验结果表明,车载经济型光纤陀螺捷联惯性测量系统满足“动中通”系统的使用要求。Strapdown inertial measurement system is an important part of"mobile satellite communication"system(mobile satellite ground station communication system).The strapdown inertial measurement system can measure the attitude and heading information of the vehicle body in real time,so that the"mobile satellite communication"system can control the antenna to point to the satellite accurately and realize satellite communication during vehicle movement.The traditional vehicle integrated strapdown inertial measurement system integrates three laser gyroscopes,which is expensive and bulky.Aiming at the problem of high price of laser gyro strapdown inertial measurement system,medium precision fiber optic gyro is selected to replace laser gyro,and the design of fiber optic gyro inertial measurement system is carried out.The system composition,component selection and design,system algorithm,structure design,economy and other design contents are described.Compared with laser gyro strapdown inertial measurement system,the designed vehicle economical fiber optic gyro strapdown inertial measurement system has smaller volume and significantly lower hardware cost.The test results show that the vehicle economical fiber optic gyro strapdown inertial measurement system meets the requirements of"mobile satellite communication"system.
