| 摘 要： | 角峪铁矿普查项目采用现代大地测量的方法，利用已知的3个D级GPS点，以E级GPS控制网作为测区首级控制网，选用6个E级点构成骨架网，按照 GPS 网的效率、可靠性、精度，进行优化设计。在四等水准点的基础上，高程测量采用GPS拟合高程的方法。结果表明，应用此方法构造的 E 级控制网，精度完全符合矿区普查的需要。

| Abstract: | In the exploration project of Jiaoyu iron deposit,by using modern geodesy measurement method, using three already known GPS points with D level,regarding GPS network with E level as the first con-trolling network,choosing six points to set up skeleton of network,in accordance with reliability indica-tors,accuracy indicators,efficiency indicators of GPS network,design has been optimized as well.On the basis of fourth grade leveling points,the GPS elevation fitting is used in height determination.The results show that the precision of the control network with the E level which is constructed by using this method can meet the demand of general survey in iron mine. |
