摘要
定向测量中定向边的坐标方位角大多使用已知边的坐标方位角和陀螺方位角来计算,根据真北与坐标北的几何关系,还可以使用已知边的真方位角和陀螺方位角来计算。文章通过对两种计算方法的结果进行对比分析,论证了基于已知边真方位角利用陀螺方位角求取定向边的坐标方位角这一计算方法的可行性。
In the orientation survey,the coordinate azimuth angle and gyro azimuth of the known side can be used for the calculation of coordinate azimuth angle of orientation side. According to the geometric relationship between true north and coordinate north direction,the true and gyro azimuth of the known side can also be used for the calculation of coordinate azimuth angle of orientation side. By comparing and analyzing the results of the two calculation methods,the method of calculating the coordinate azimuth angle of orientation side with the true and gyro azimuth angle of the known side is proved to be feasible.
