| 摘 要： | 首先阐述了水深测量的两种作业模式：传统人工验潮水深测量和GPS无验潮水深测量，对两种作业方式作了简单的比较。简要介绍了GPS精密单点定位（PPP）的基本原理，给出了GPS无验潮水深测量数学模型。然后，针对传统水深测量作业模式的弊端，提出采用GPS精密单点定位技术进行无验潮水深测量作业，并从静态和动态定位两个方面验证了PPP技术进行无验潮水深测量作业的可行性。

| Abstract: | Firstly,this paper expatiates on the two surveying models of hydrographic,and then analyses these.We describe briefly the basic principle of GPS Precise Point Positioning(PPP),then present the model of hydrographic surveying using GPS.Contraposing these problem,we put forward to accomplish the work of sounding based on PPP without tide gauge,moreover we validate the feasibility according to this method from the aspect of static and dynamic positioning. |
