摘要

介绍了GPS测量方位角的原理与方法。使用GPS测量了琼中地震台4个观测墩的方位角,取得较好的结果,并对测量结果的精度和误差来源进行了分析。结果证明,GPS测量方位角方法不受观测时间限制,受天气影响较小,对人员要求不高,观测时间只需2～3天,具有较大的应用前景。
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.
