差分GPS和全站仪在水下地形测量定位精度探讨

Discussion on the Positioning Accuracy of DGPS and TS (Total Station) in Underwater Topographic Surveying

ＤＧＰＳ和全站仪在水下地形测量中应用已十分广泛，但对其定位精度的探讨分析不足通过实验为以ＤＧＰＳ、全站仪在水下地形测量的定位精度提供了可信的理论依据，对拓展ＤＧＰＳ使用范围有一定的指导意义．

DGPS and TS (total station) have widely been using in underwater topographic surveying. There is, however, lack of discussion and analysis of their positioning accuracy. This paper provides reasonable theoretical basis for the positioning accuracy of DGPS and TS in underwater topographic surveying and it shows some guidance to extend the DGPS application.
