摘　　要：在无验潮测量后处理过程中,采用不同的软件对成图的精度有着不同的影响。采用的无验潮测量软件是在中海达测深软件的基础上自主研究的一款"长江江苏无验潮高程拟合"软件,结合无验潮水深测量原理,在长江江苏段对该软件处理的水深结果进行精度测试,测试结果表明,系统的精度是符合无验潮测量系统水位精度不得大于5 cm的设计要求。In the post-processing of non-tidal observation measurement,the application of different software has different influence on the precision of the drawing.In this paper,the non-tide observation measurement software is a self-study software of"Yangtze river Jiangsu non-tidal elevation fitting"based on the Zhonghaida sounding software.Combined with the non-tidal depth measurement principle,the accuracy of water depth results by this software were tested in Jiangsu section of Yangtze River.The test results showed that the accuracy of the system was consistent with the water level accuracy of non-tidal observation measuring system,which should not exceed 5 cm.
