In plotting scene, the invention connects fiber-optic gyro(1) with full station instrument telescope(3) by adaptor(2), and make optical fibre gyro can follow full station instrument telescope simultaneously do 180 degree turning reel full station instrument cross shaft, respectively on two horizontal positions of east and west direction of gyro axis that differ by 180 degree; each horizontal position process 2 x 2 position gyro data acquisition on full station instrument perpendicular tray that differ by 180 degree; using formula to count out full station instrument collimation axis true azimuth, survey station meridian convergence angle, then can obtain full station instrument collimation axis grid azimuth, realize full station instrument orient.

基于光纤陀螺的全站仪组合定向方法是一种应用于测绘工作的基于光纤陀螺的全站仪组合定向方法，该方法在测绘现场，把光纤陀螺(1)通过连接装置(2)与全站仪望远镜(3)固连，使光纤陀螺(1)可随全站仪望远镜(3)绕全站仪横轴(4)同步做180度转动，分别在陀螺轴东西向相差180度两个水平位置，每个水平位置在全站仪竖盘相差180度的两个竖直位置进行2×2位置陀螺数据采集；利用公式算得全站仪视准轴真方位角、测站子午线收敛角，即可进一步获得全站仪视准轴坐标方位角，实现全站仪定向。

Making use of structural characteristics of the Lower Latitude Meridian Circle and the error theory of this instrument, we have developed a method used to measure directly instantaneous atmospheric refraction, and moreover built a local observational astronomical refraction model toward the east, south, west and north of Yunnan observatory that is classified according to the star's spectral type.

阐述了云南天文台探讨出的利用低纬子午环的观测原理，在不同方向和不同天顶距直接测定瞬时大气折射值的一套方法，并给出了用实测数据在东、南、西、北4个方向建立的按恒星光谱型分类的大气折射实测模型。
