摘　　要：介绍了陀螺经纬仪定向与天文方位角传递定向的基本原理,讨论了两种定向方法结果的一致性。通过实验验证,在一定的条件下,两种定向方法结果一致,都可应用于高精度定向,天文方位角定向一般作为陀螺经纬仪仪器常数标定的基准,在定向精度要求3″及以下时,建议广泛采用陀螺经纬仪进行定向测量。This paper introduces basic principle of the gyro theodolite orientation and the astronomical azimuth transmission orientation and discusses the consistency of the directional results of two kinds method.Experiments show that under certain conditions,two kinds of directional results are consistent and both can be used in high precision orientation.The astronomical azimuth orientation can be regarded as standard of calibration for the constant of the gyro theodolite instrument,and the gyro theodolite directional methods should be adopted widely when directional accuracy is not less than 3″.
