【摘要】 本文通过对惯性器件输出误差的分析,描述了单轴旋转惯导系统自动补偿的基本原理;通过分析陀螺漂移产生的导航误差产生机理,得到陀螺误差随转速的变大而变小的结论;利用光纤陀螺捷联惯导系统进行了单轴旋转实验,证实了上述分析结论。研究结果对单轴旋转系统转速的选择提供依据,并可为双轴旋转系统的开发提供参考。更多还原

【Abstract】 Through the analysis of inertial instruments output error,the basic principles of automatically compensation of single-axis rotary inertial navigation system have been introduced.By analyzing the principle of the gyro drift error,we’ve got the conclusion that with the rotational speed getting bigger,gyro error becomes smaller.By making use of fiber optic gyro strapdown inertial navigation system to do the single-axial rotation experiment,the conclusions of the above analysis are confirmed.The results provide a basis for single-axis rotation speed and a necessary reference for the development of two-axis rotation system.更多还原
