| 摘 要： | 对2009年汛后黄河河口清+3—清+6断面GPS-RTK联机测量河道断面数据的情况进行了分析,结果表明:单次测量的平均误差为-0.034～0.013 m,单测次的中误差为0.041～0.068 m;在124个测点中,误差小于0.05 m的测量数据占全部数据的62.90%,误差小于0.10 m的占91.90%,误差大于0.10 m的比例约为8%;水温、声速、波浪等误差是测深误差的主要来源。

| Abstract: | The riverway section survey data of the Qing+3-Qing+6 sections of the Yellow River estuary after the 2009 flood season,collected with GPS-RTK on-line measuring method were analyzed in this paper.The results show that the average error of single measurement is-0.034-0.013 m and median error of single measurement is 0.041-0.068 m.In 124 stations,the stations those error is less than 0.05 m account for about 62.90%,the stations those error is less than 0.10 m are about 91.90%,while the stations those error is ... |
