摘要
以高导磁环型磁芯为敏感元件,设计了正交磁通门罗盘,改进正交磁通门探头的传统工艺。基于二次谐波法原理,设计硬件电路实现水平航向角度值的测量。实验结果表明:测量最大误差为3°,满足导航性能要求。
Design an orthogonal fluxgate compass which use high-permeability ring-type magnetic core as sensitive element,improve traditional handicraft of orthogonal fluxgate probe. Based on principle of quadratic harmonics,hardwire circuit implements measurement of horizontal heading angle. Experimental result show that the maximum error of measurement is 3° which can satisfy performance requirement of navigation.
