近年来，全球定位系统(GPS)技术迅猛发展，由于它具有连续、实时、高精度、全天候的特点，使其在诸如测量、定位、导航中得到广泛应用。MD300测深系统是在GPS支持下的一种全新的水域地形测量系统。结合长江委荆江水文水资源局对该系统的开发、应用，介绍了其结构功能、系统配置及实现方法，从实际运用效果看，与常规测量方法相比，该系统具有定位精确、水深采集准确、自动化程度高等特点，是理想的河道测绘系统。
近年來，全毬定位繫統(GPS)技術迅猛髮展，由于它具有連續、實時、高精度、全天候的特點，使其在諸如測量、定位、導航中得到廣汎應用。MD300測深繫統是在GPS支持下的一種全新的水域地形測量繫統。結閤長江委荊江水文水資源跼對該繫統的開髮、應用，介紹瞭其結構功能、繫統配置及實現方法，從實際運用效果看，與常規測量方法相比，該繫統具有定位精確、水深採集準確、自動化程度高等特點，是理想的河道測繪繫統。
근년래，전구정위계통(GPS)기술신맹발전，유우타구유련속、실시、고정도、전천후적특점，사기재제여측량、정위、도항중득도엄범응용。MD300측심계통시재GPS지지하적일충전신적수역지형측량계통。결합장강위형강수문수자원국대해계통적개발、응용，개소료기결구공능、계통배치급실현방법，종실제운용효과간，여상규측량방법상비，해계통구유정위정학、수심채집준학、자동화정도고등특점，시이상적하도측회계통。
In recent years,the global positioning system(GPS) technique is rapidly developing,since it is characterized by continuity,real-time,all-weather operation with high accuracy,this technique has found extensive application in survey,positioning,navigation.MD300 sounding system is a new topograpbic survey system especially for water areas supported by GPS.In combination with the development and application of the sounding system carried out by the Jingjiang Investigation Bureau of Hydrology and Water Resources of Changjiang Water Resources Commission,the structural function and system configuration and the implementation methods of the system are presented.From the viewpoint of its practical effect of application,this sounding system has characteristics of accurate positioning,accurate water depth acquisition and high automation procedure,compared with conventional metheds.The system is an ideal river channel mapping system.
