基于GNSS浮标的实时水深船舶导航模型

Ship Navigation Model of Real-time Channel Depth Based on GNSS Buoy

在海洋航行中,航道海水深度的预报对保证航海安全和航道的充分利用具有重要意义。通过在航道海面布设一些GNSS浮标,实时测定浮标所在位置海水面的高度,借助数据链,将经数据处理中心处理后的浮标实时水深传播给用户船舶,借以对船舶进行导航。对该导航模型的原理和方法及可行性进行了阐述。

In an ocean voyage,the prediction of seawater depths in navigation channels is very im-portant to ensure the full use of channel and safety of navigation.To measure the real-time sea surface height,the GNSS buoys are set at sea surface.The survey data are transmitted to data processing center through the data chain,and ships can receive the processed data from the data processing center to guide them in sailing.In this paper,the principles and methods of the ship navigation model are expounded.
