GPS测定正常高程可行性研究与控制测量应用

全球定位系统(GPS)是美国军方研制组建的新一代卫星导航定位系统,与常规大地测量手段相比,GPS定位技术具有全天候、站间无需保持通视、可同时测定点的三维坐标、精度高、费用省等优点。当前,GPS平面控制网已得到了广泛的应用,同时经过实验测试,在平原或浅丘地区,在不加地形改正的情况下,拟和出的正常高高程可以满足一般工程和大比例尺测图的要求,在一定程度上降低了生产成本。

Feasibility Study and Application of Control Surveying of Measuring Normal Elevation Using GPS

The Global Positioning System(GPS) is the new generation of satellite navigation positioning system developed by the American military.Compared with the convention geodetic survey method,the GPS localization technology has the advantages of interstation all-weather,does not need indivisibility between two stations,measuring the three dimensional coordinates of a station at the same time,high precision,and so on.Presently,the GPS horizontal control network obtained the widespread application.Meanwhile,based on the experiment,in the plain or the shallow earthen mound area,it can draws up with the normal high regulation which may satisfy the general engineering and the big scale mapping request,and can reduce the production cost in the certain degree.
