Gao Cheng-fa · Port & Waterway Engineering · 2003
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.
