陆用光纤陀螺寻北仪误差特性研究
|
摘要
针对陆用武器对高精度寻北定向的要求,本文以高精度光纤陀螺寻北仪为研究对象,基于光纤陀螺寻北仪误差模型和光纤陀螺的误差特性,从理论上对光纤陀螺寻北仪寻北误差进行了分析,提出寻北仪主要包括系统误差和器件误差两个方面的误差源,并分别对不同误差源引起的寻北误差进行推导,得到光纤陀螺寻北仪寻北精度主要受陀螺零偏漂移、安装误差和转台测角精度决定的结论。对光纤陀螺寻北仪各误差源引起的寻北误差进行仿真试验,试验证明了理论分析的正确性。
Aiming at the requirement of land weapons for high accuracy north seeking,taking high accuracy FOG north-seeker as the research object,based on error model of FOG north-seeker and error characteristics of FOG,the error of FOG North-seeker is analyzed in theory,and error sources of north-seeker are introduced,which mainly include system error and device error. The north seeking errors caused by different error sources are deduced,the results show that north seeking precision of FOG north-seeker mainly depends on gyro drift,installation error and angle measurement accuracy. The simulation experiment on north seeking error caused by various error sources of FOG north-seeker was carried out. The experimental results prove the validity of the theoretical analysis.
