为了说明VRS（Virtual Reference Stations）技术可应用于长距离油气管道工程测量，对比了传统RTK(Real Time Kinematic)技术与VRS技术的工作原理和各自优势。在管道工程测量实践中，通过VRS技术检核GPS静态控制点，平面和高程的较差不超限，其精度满足相关测量规范要求，且提高了测量作业效率。VRS技术简单、实用，可以用于碎部点采集和施工放样，在测绘及油气管道工程领域的应用前景广阔。

In order to prove that VRS (Virtual Reference Stations) technology can be used in long distance oil and gas pipeline engineering survey, compared are principles and advantages of convectional RTK (Real Time Kinematic) technology and VRS technology. In the practice of pipeline engineering survey, checked are CPS static control points by using VRS, the difference in horizontal direction and vertical direction do not exceed limitation and meets relevant requirements of standardized measurement technology and measurement efficiency is improved greatly. VRS technology can be used for detail point collection and construction lofting. VRS technology has such features as simple operation and strong practicability and can provide great convenience for construction personnel in any area where the technology can be used in measurement.
