摘要
为了将磁通门罗经检测的地磁航向信息转换为方便微机处理的数字量,将跟踪式航向解算方法应用于磁通门罗经。分析了磁通门罗经的工作原理和地磁航向信号形式;阐述了跟踪式航向解算方法的基本思想;给出了实验测试数据。测试结果表明:采用跟踪式航向解算方法的磁通门罗经的航向精度满足地磁罗经精度要求。
In order to convert geomagnetic azimuth information detected from fluxgate compass into digital number for computer to process conveniently, tracking azimuth calculation method is applied to fluxgate compass. The principle of fluxgate compass and the geomagnetic signal are analyzed, and then the basic theory of tracking azimuth calculation method is described. The experimental data are given. The experimental results show that azimuth accuracy of fluxgate compass using tracking azimuth calculation method meets the accuracy requirements of geomagnetic compass.
