GPS-RTK配合全数字测深仪在南海涂围垦工程中的应用

Application of GPS-RTK with All-digital Sounder in Reclamation Engineering

采用先进的GPS-RTK技术配合内置导航软件和测深软件的全数字测深仪进行作业.既可满足精度的需要,也简化了作业过程,提高了效率.在对南海涂围垦工程进行水下地形测量、水下断面测量等方面的具体应用中,分析论证了影响水下地形测量精度的一些因素并提出了相应的应对措施.由此凸显出GPS-RTK配合全数字测深仪进行水下地形测量作业的极大优越性,并证明该项技术手段先进,方法可行.

The application of GPS-RTK, along with all-digital depth sounder inserted by navigation software, is introduced in the paper, which is easy to operate with high efficiency and precision. Take Southern Reclamation Engineering for example, the application of GPS- RTK with all-digital sounder shows its relative advantages in subaqueous topographic survey compared with those in subaqueous crosssection smvey. Some aspects resulting in poor precision of subaqueous topographic survey are analyzed and the countermeasures are also discussed.
