摘要
目前,将差分GPS水深测量系统运用到航道普查还是一次新的探索。本文在简要介绍了该系统的硬件组成、差分GPS的基本定位原理后,重点介绍了利用该系统进行航道普查的作业流程以及注意事项。这一工程实践经验对今后我国沿海地区的航道普查和航道信息的及时更新具有一定的借鉴作用。
At present, to apply the differential GPS bathymetric survey system in channel general survey is still a new trial. After introducing the hardware composition of the system and basic positioning principle of differential GPS, this paper mainly introduce the operation flow and matters needing attention of the system during channel general survey. The experience of the engineering practice may serve as a reference for channel general survey and updating of channel information of the coastal areas in China.
