摘　　要：文章分析了传统天文方位角测量的方法及存在的缺点,首次提出了用GPS授时,电子经纬仪进行角度观测的测定一、二等天文方位角的方法。阐述了此方法的实施过程及解算原理,进行了精度估计,并以实际测量结果进行了验证。This paper analysed the method and weakness of the traditional observation for astronomical azimuth firstly. Measurement of first or second level astronomical azimuth by using GPS and electronic theodolite have been brought forward for the first time. Course and calculating principle and accuracy of this method have been discussed. This method have been proved to be viable through geodesic results.
