2) Gyro north direction value
陀螺北方向值
1.
In this paper,the mathematical formula of Gyro north direction value ,the theoretical precision,limiting error of observed value and calculated value and mean square error of a measurement in the orientation by using transit method are described.
本文论述了中天法定向时陀螺北方向值的计算公式、理论精度、观测值及计算值的限差；一次测量中误差，并以ＷＩＬＤＧＡＫ１陀螺经纬仪为例进行了实际定向，且与理论精度进行了比
3) gyrocompass north
陀螺罗北
5) gyro-positioning
陀螺定向
1.
However,by applying gyro-positioning technique to locate artificial magnetic field,the ultrasound imaging produced by measurement processing,where AC(Alternating Current) signal is induced by rotated coils in the artificial magnetic field as the triggering signal for image scanning,can quickly and accurately ascertain the fault.
为解决这一问题,文章运用陀螺定向技术对人造磁场进行定向,转动的线圈在人造磁场中,感应出来的交变电信号作为图像扫描触发信号,同样能形成超声图像。
6) Gyro orientation
陀螺定向
