| 摘 要： | 以500 kV库湾至曲江、库湾至汾水解口输电线路控制测量为例,分析比较CORS和快速静态测量两种不同作业模式,在已知点残差、控制点平面和高程精度等方面的差异。结果表明,在较长的带状地形控制测量中,CORS平面精度与快速静态基本一致,高程精度优于后者。故在类似工程中CORS可取代常规快速静态测量。

| Abstract: | Taking the control surveying of 500 kV transmission line from Kuwan to Qujiang and Fenshui fork as an example,we analyze and compare two different operation between modes CORS and rapid static measurements,in residual the known points,plane and elevation precision of the control points,etc.The comparison results show that in the longer ribbon terrain control surveying,CORS basically has the same precision with the rapid-static in plane,but better than the latter in elevation.So in the similar projects,CORS could replace the conventional rapid static measurement. |
