激光陀螺仪惯性导航教学实验平台开发

Development of Laser Gyroscope Inertial Navigation Teaching Experiment Platform

针对现有惯性导航实验教学平台的仪器设备价高量少的状况,设计了一种面向实验教学的激光陀螺仪惯性导航平台。该平台包含激光陀螺仪、电动转台、控制器、数据采集软件、计算机等。开展了激光陀螺仪的驱动及控制、激光陀螺仪与电动转台的标定、激光陀螺仪角速率数据采集软件的开发及优化实验。结果表明:该教学平台具有成本低、精度高、开源性好等优点,可以广泛应用于本科和研究生教学。同时开发了用于实验教学的激光陀螺仪的器件特性、多位置寻北等系列实验,零偏稳定性达到0.01°/h,寻北误差<0.064°。

Aiming at the high cost and low quantity of the existing inertial navigation experiment teaching platform,a laser gyroscope inertial navigation platform for experimental teaching is designed,which includes laser gyroscope,electric turntable,controller,data acquisition software,computer and so on.The drive and control of the laser gyroscope,the calibration of the laser gyroscope and the electric turntable,the development and optimization experiment of the software of angular rate data acquisition of the laser gyroscope are carried out.The results show that the teaching platform has the advantages of low cost,high precision and good open source,and can be widely used in undergraduate and graduate teaching.At the same time,a series of experiments on the device characteristics and multiposition north finding of the laser gyroscope for experimental teaching are developed.The zero bias stability reaches 0.01°per hour and the north finding error reaches 0.064°.
