Abstract:

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.

Key words: GNSS, acoustic positioning, seafloor control network
