摘要
通过实例,分析了在没有重力勘测资料和地球重力场模型的情况下,利用GPS高程拟合解决架空输电线路工程的高程控制测量,从而满足架空输电线路工程中平断面图的高程测量精度要求;为提高GPS高程拟合精度,提出了在架空输电线路勘测工程中应注意的问题及经验。
The article analyzed the examples, application of the GPS height simulation solved height control survey on the overhead transmission line without data of gravity survey and the earth gravitational field model. It satisfied the precision requirement of height survey in the plane of circuitry engineering. For improving the precision of GPS height simulation, several important questions and some experience were presented that shoud be payed attention to for the overhead transmission line project.
