摘要
重点介绍了ＧＰＳ测量代替常规水准实现高程控制的方法和措施。给出了用ＧＰＳ技术代替常规水准的数学处理模型，并通过几个实际工程测量实例进行了误差分析，证明该方法切实可行。
A lot of GPS control surveying and data processing were done. The horizontalcontrol and height control are all successful. This paper introduces the replacement method ofconvent levelling by GPS levelling.The numerical model for replacing convenient levellingwas given. The surveying errors were analyzed. The practice shows that the method isreasonable.
