积分法在智能陀螺寻北系统中的应用研究

Application of integral method in all automated intelligent gyroscope north finder

寻北方法是陀螺寻北仪的重要研究对象。在分析智能陀螺寻北系统的光路及采集系统基础上,对积分法进行了深入的理论分析,并讨论了其在智能寻北系统中的应用研究。利用JT—15型陀螺寻北仪,分别用中天法和积分法进行了寻北测量的对比实验,中天法测量的标准偏差不超过11,″积分法测量的标准偏差不超过9″。实验结果表明:积分法可以得到比中天法高的测量精度,在全自动智能寻北系统中可替代中天法进行寻北测量。

North-finding method is an important research of gyroscope north finder. Based on the analysis of optic block and acquisition system of intelligent gyroscope north finder,the integral formula adapting to north finding is deduced and is applied in all automated intelligent gyroscope north finder. The experiments of transit method and integral method are respectively designed. Using the JT-15 gyroscope north finder,the standard deviation of the experiment of transit method, full-period integral method and half-period integral method is respectively 11″and 9″. The result of the experiments shows that the precision of integral method is higher than that of traditional transit method.
