GAK-1陀螺经纬仪在不同经纬度地区定向研究
Orientation research of GAK-1 gyrotheodolite in different latitude and longitude regions
摘要
Abstract
Gyroscopic orientation survey,as an important link in ensuring the continuity of underground engineering,involves calculating the convergence angle of meridian from geodetic coordinates.Due to the involvement of too many parameters and the need for multiple iterations,the calculation is particularly cumbersome and complex,which adds great difficulty to on-site engineering applications.The a-dopted meridian convergence angle coefficient method effectively solves this problem.Precise orientation was determined by combining the GAK-1 gyrotheodolite with the reversal point method,and the geometric relationships among various azimuth angles in gyroscopic o-rientation were analyzed.The Cartesian coordinates of different quadrants were analyzed to obtain the coordinate azimuth angle,the cal-culation formula for the meridian convergence angle in different latitudinal and longitudinal regions was provided based on the conver-gence angle coefficient table,and the directional measurement results were analyzed with an engineering example.The results indicate that the instrument constant is relatively stable when measuring in different latitude and longitude mining areas,and different latitude and longitude mining areas have a significant impact on meridian convergence angle.关键词
