Calculation of celestial body azimuth with compass error by celestial observation based on CAD 基于CAD的天测罗经差天体方位计算
The experimental results show that azimuth accuracy of fluxgate compass using tracking azimuth calculation method meets the accuracy requirements of geomagnetic compass. 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。
Application of tracking azimuth calculation method in fluxgate compass 跟踪式航向解算方法在磁通门罗经中的应用
Take celestial azimuth and find compass error on each watch if the weather is fine. 如天气好,每一班测取天体方位求出罗经差。
The Correction of Azimuth Compass Auto-aligning Principle 方位罗经自对准原理的修正
The reason why they are flaws and the more suitable statement about azimuth compass alignment are provided. 分析了原因,并给出了方位罗经对准原理更确切的描述。
The surveying outcome indicates that the instrument performance is stable and the instrument's standard deviation of azimuth determination is ≤± 30 ′ and the instrument can replace the magnetic compass and the instrument can carry out directional survey of lower precision. 测试结果表明,仪器性能稳定,陀螺方位角一次测量中误差≤±30′,可以替代磁罗盘,进行低精度的定向测量。
The second is that the level circuit adopted by azimuth compass aligning circuit can only be two-order and can't be three-order, but as a matter of fact, three-order level circuit can be adopted in azimuth compass alignment. 方位罗经对准回路中,水平回路只能采用二阶调平回路,而不能采用三阶调平回路,而事实上采用三阶调平回路照样可以实现方位罗经自对准。
