关于我国区域海洋无缝垂直基准建模及其转换方法的探讨

摘要

With the improvement of the global navigation satellite system (GNSS) and increasing amount of oceanographic projects, the accuracy requirement of the local marine vertical datum modeling and transforming has become continuously higher..The paper involves a discussion on the current situation of domestic marine seamless vertical datum system in Chinese local sea.Besides, a summarized introduction about the establishment of related models and the transformation method amongst marine vertical datum are also contained, coupling with an instance analysis, which renders technological reference for researchers in related realm.%随着全球导航卫星系统(GNSS)的完善,以及海洋工程的日趋增多,对于区域海洋无缝垂直基准建模及其转换精度的要求也不断提高.本文针对建立我国区域海洋无缝垂直基准体系的现状进行探讨,概要性地介绍了有关模型的建立和海洋垂直基准间的转换方法,并配案例,为相关领域的研究者提供了技术参考.
