海底大地测量控制网研究进展综述

高精度的海底大地测量控制网是数字海洋和水下网络中心战的基础设施之一，而现阶段我国海底控制网的建设和研究几乎为空白。为自主建立我国高精度的海底大地测量控制网，本文借鉴发达国家的经验，结合国外海底控制网的发展与研究现状，系统介绍了GNSS/Acoustic系统的组成及发展；详细梳理了数据处理中的关键技术，分析了影响海底控制点精度的因素和控制点定位精度；结合我国现状，建议加紧开展我国海底控制网的建设与研究。

Summary of the Research Progress of Seafloor Geodetci Control Network

The high-precision seafloor geodetic control network is one of the infrastructures of digital ocean and underwater network centric warfare.However, the construction and research of seafloor control network at present is almost blank in China.To autonomously establish high-precision seafloor geodetic control network, this paper draws on the experience of the developed countries.Firstly, the development and current situation of the foreign seafloor control network are combined, and the composition and development of GNSS/Acoustic system are introduced systematically.Then the key technologies of data processing are studied in detail, the factors that affect the positioning accuracy of seafloor control point and its positioning accuracy are analyzed.Finally, taking the present situation in our country into account, immediate steps should be taken to speed up the construction and research of the seafloor control network.
