测量船动态吃水测量方法研究

The Measurement Method Research of Dynamic Draft of Survey Vessel

针对测量船特别是中大型测量船的动态吃水问题,提出了单船和双船载波相位差分GPS测定方法,给出了动态吃水计算公式。根据装备现状,对比分析了三种测量方法的适用范围,例举了典型参数值的动态吃水观测误差,旨在为测量作业人员提供借鉴和参考。

According to the dynamic draft problems especially the medium and large-sized survey vessel, the single and double ship RTK GPS measurement method is put forward, and the calculation formula of the dynamic draft is given. According to the equipment＇ s present situation, the author compares three kinds of measurement methods, analyzes their application scopes, and describes the observation error of the typical dynamic draft in parameters values to provide some experience and reference for the surveying workers.
