| 摘 要： | 针对远海航渡式水深测量作业中的潮汐改正难题,基于全球潮汐场DTU10模型及GPS无验潮测深两种改正模式,通过潮汐场预报精度评估、验潮站实测数据比对分析以及GPS大地高计算潮汐值等多种手段,开展了大范围、长时段、单测线情况下水深测量水位改正研究,形成了一套适用性强的航渡水深测量水位改正方法与流程,为面向全球的海洋水深测量资料处理提供了潮汐、垂直基准和水位归算的方法和技术支持。 |
| 关 键 词： | 航渡 水深测量 水位改正 潮汐场 垂直基准 |

| Abstract: | In order to solve the problem of tidal correction in bathymetric survey along the open-sea route , and based on two correction modes of global tidal field model DTU10 and GPS without tidal observation, the research on waterlevel correction in bathymetric survey is conducted along the single survey line in a large scope for a long period of time, to form an appropriate waterlevel correction method and flow by means of tidal field prediction accuracy evaluation, tidal gauge data analysis and tidal calculation by GPS geodetic height for providing methods and technology support of tide, vertical datum and waterlevel calculations for global hydrographic resource processing. |
| Keywords: | open-sea route bathymetric survey waterlevel correction tidal field vertical datum |
