摘　　要：CORS基准站高程的准确性直接影响CORS应用高程测量的精度,基准站的高程通常采用精密几何水准测量,高楼和高墩采用吊铟钢尺方式进行测量,作业方法繁琐、工作量大。本文进行了对向精密三角高程观测方法的分析,并应用于CORS基准站的高程测量,取得了良好的效果。CORS reference station elevation accuracy directly affects the accuracy of CORS application. Leveling el-evation of reference stations usually measuring by Geometric precision level. Tower and high pier using invar rod hanging way to measure,operating methods complicated,heavy workload. In this paper,on the precise trigonometric methods of observation analysis and height measurement for CORS reference stations,and achieved good results.
