浅谈GPS在高等铁路平面控制测量中的应用

Tentative discussion on the application of GPS in the higher railway horizontal control survey

简单介绍了GPS的基本原理,并结合某高等铁路平面控制网的测量,阐述了GPS在高等铁路平面控制测量中的应用,通过对观测数据进行处理和精度分析,指出GPS网精度高,符合规范要求,提高了工作效率,有广阔的应用前景。

With a brief introduction to the basic principles of GPS,combined with the measurement of higher railway horizontal control network,it described the application of GPS in higher railway horizontal control measurement,by dealing with the observing data and analyzing them sophisticatedly,and then pointed out that GPS network with high precision can meet regulatory requirements and improve efficiency,and will have a broad application prospect.
