YANG Wen-fu,CUI Yu-zhu(Coal Geological Geophysical Exploration Surveying & Mapping Institute of Shanxi Province,Jinzhong 030600,China)  
This paper studies the surveying principle,error analysis and parameter conversion of GPS-RTK briefly,and introduces the GPS-RTK elevation surveying method.Some questions are pointed out that should be paid attention in GPS-RTK elevation surveying by analyzing and comparing high precision total station observation data with GPS-RTK elevation measurement data.Some effective measures of improved GPS-RTK elevation measurement are presented to overcome these problems in productive practice.The aim is to widen the application of GPS-RTK technology and improve its measurement precision.
