黑洼水库地区GPS平面控制网的布设与实施

GPS Horizontal Control Network's Layout and Surveying in the Area of Heiwa Reservoir

运用GPS相对静态测量技术,按照D级GPS控制网的要求,采用边连式的布网方案,设计并实测了黑洼水库地区GPS平面控制网,再通过LGO等数据处理软件进行控制网平差,获取该平面控制网的坐标数据。该GPS平面控制网的建设将为黑洼水库地区的规划建设和地形测量提供基础资料。

The paper researches GPS horizontal control network＇s layout and surveying in the area of Heiwa reservoir in Chuzhou city of Anhui Province ,designs the best GPS control network type layout scheme and uses the edge connected style of operation modes ,GPS static relative positioning technical and the adjustment processing of LGO software to obtain the coordinates of the horizontal control net-work data .In the meantime ,the accuracy of data is analysed .
