| Abstract: | The principles and methods of astronomical azimuth surveying by GPS were introduced. The azimuths on four instrument frusta in Qiongzhong Geomagnetic Station were measured with GPS survey methods. The measurement gained better results. The precision and error source of the measurement results were analyzed. The survey of azimuth with GPS methods is not limited by measurement time, weather and observers,and needs only 2-3 days of measure time. The method has a good application prospect. |
