GPS-RTK无验潮技术在水下地形测量中的应用

Application of Non-inspecting Tidewater Technology of GPS-RTK to Surveying the Terrain under the Water

GPS-RTK无验潮水下地形测量技术能够实时提供流动站在指定坐标系中的三维定位结果,解决水位不断变化的问题,能够实时测出测点处水面高程,并在一定范围内达到厘米级实测精度。这种技术在水下测量中的应用,与传统方法相比有很多优点。

The non-inspecting tidewater technology of GPS-RTK in surveying the terrain under the water can supply the operating station for three-dimensional locating result in the specifying coordinate system to solve the problem of water level changing constantly,can survey the altitude of water surface at the real time on the spot of surveying point and reach to the really accurate surveying degree of centimeter in the certain scope.This kind of technology has many advantages compared with the traditional methods in surveying the terrain under water.
