Based on the Instrument Control Toolbox in Matlab, DGPS signal data can be received via the serial port, so this technique can be used for real-time visualization in ship-mounted ACDP survey. The method was tested at Zhoushan sea area for 28-hour continuous ship-mounted ADCP observation. During the test, the real-time visualization system worked fine, tracks of DGPS, the speed of the vessel, and the direction of the vessel renewed automatically every second, which was satiable the requirement of real-time visualization. The only thing we need to do before the survey is to prepare one background map, the system is stable and is easy to use, and the most important, the system workes stably during the 28-hour observation.
