摘　　要：采用计算方位和测量舷角相结合的方法进行真航向测量时,由于舰船安装条件有限,舰位测量设备DGPS和经纬仪不可能安装在同一位置。直接将DGPS测量的舰位作为经纬仪中心的位置会影响到方位角的计算结果,进而影响航向测量精度。本文采用归心改正理论根据DGPS测量的舰位推算经纬仪中心的精确位置,根据此位置计算出的岸标真方位的精度得到了提高,最终提高航向测量的精度。When true course was measured by the method of combining computed azimuth with measured bearing, as ship position measurement instruments DGPS and theodolite were not installed in the same position because of the limit installation conditions. If the position measured by DGPS was regarded as the central position of the theodolite, the computational result of the azimuth would be affected and even the measurement accuracy of the course was affected. This paper used Regress-to-center theory to calculate the accurate central position of the theodolite on the basis of the measurement result by DGPS, the true azimuth accuracy of the shore beacon was improved according to this accurate position, finally the course accuracy was improved.
