高速公路征地测量中GPS-RTK技术的运用

关键词 Abstract At present GPS technology is developing rapidly and has been widely used in various fields. The application of GPStechnology in expressway land expropriation measurement has improved the survey precision and surveying efficiency greatly especially thedevelopment and progress of GPS -RTK technology which is more and more widely applied in the field of conventional highwaymeasurement. This paper mainly introduces the working principle and characteristics of GPS-RTK technology and its application andanalyzes the advantages of DPS-RTK technology in precision and timeliness.院高速公路 征地测量 GPS&mdash RTK 技术 运用Key words expressway land expropriation measurement GPS-RTK technology application中图分类号院P228.4 文献标识码院A 文章编号院1006-4311（2014）27-0232-02
