| Abstract: | This paper reviews the applications of the Doppler positioning and GPS satellite positioning technology in China＇s hydrographic surveying and charting, and gives that the GNSS will become a new application window on China＇s future hydrographic surveying and charting in following several aspects：firstly, navigation satellite will bring importance into play for constructing the powerful sea nation. Secondly, GNSS triple frequency receivers will create a new chapter for sea measurements. Finally, GNSS navigation satellites can be used to provide the higher accuracy in on-the-fly 7 dimensional state parameters and 3d posture parameters for airborne laser sounding system. |
