【摘要】：GNSS PPK(post processing kinematic)技术属动态后处理技术,不受电台无线电传播距离的限制,有效作用距离可达80 km。为解决沿海长航道水深测量需在海上设置定点验潮站的难题,提出基于Hypack 2014的GNSS PPK三维水深测量方法。该方法无需进行水位提取与水位拟合,提高了水深测量精度;且采用现有商业软件TBC和Hypack,避免了繁琐的二次开发。介绍GNSS PPK定位原理及GNSS PPK三维水深测量工作原理,阐述基于Hypack 2014的GNSS PPK三维水深测量的实施方法,在沿海长航道水深测量方面具有推广价值。
[Abstract]:GNSS PPK(post processing kinematic) is a dynamic post-processing technology, which is not limited by radio transmission distance. The effective working distance can be up to 80 km. In order to solve the problem of setting up fixed tide stations at sea in order to solve the problem of water depth survey in coastal long channel. A GNSS PPK 3D bathymetric method based on Hypack 2014 is proposed, which does not need water level extraction and water level fitting, and improves the precision of bathymetric measurement. The existing commercial software TBC and Hypackare used to avoid the complicated secondary development. The principle of GNSS PPK positioning and the work principle of GNSS PPK 3D bathymetry are introduced. This paper expounds the implementation method of GNSS PPK 3D bathymetry based on Hypack 2014, which is worth popularizing in coastal long channel bathymetric survey.

【正文快照】： 对于沿海长航道水深测量,当测区超出岸边水位站有效控制范围时,可在海上设立临时水位站(修建验潮站、抛压力式验潮仪)、潮位推算,或直接进行GPS RTK三维水深测量。但海上修建验潮站的难度大、成本高,因此较少采用;抛压力式验潮仪则会面临验潮仪丢失或由于仪器在海底滑动导致采，
