摘要
利用单基站RTK、全站仪的传统测量技术已经不能适应工程建设的需要,特别是给线性工程(市政大道、高速公路、高速铁路)的土地勘测定界测量带来极大困难,而连续运行卫星定位综合服务系统(简称CORS系统)技术解决了传统测量技术受放样线路长、设站转站多、累积误差大等限制。文章通过CORS系统技术在线性工程土地勘测定界测量中的应用实例进行研究,结果表明:CORS系统有效覆盖距离大,提高放样测量的精度,改变了传统RTK测量的作业模式,简化了测量流程,节省了测量时间,提高了生产效率。文章阐述了CORS系统的组成和优势,介绍了CORS系统技术在土地勘测定界测量中的应用案例,统计了土地勘测定界测量的精度。
The use of single base station RTK,full station of traditional measurement technology has been unable to meet the needs of the engineering construction,especially for linear engineering(municipal avenue,highway,high-speed railway)land survey boundary measurement brings great difficulties,and continuous operation of satellite positioning integrated service system(CORS system)technology solved the traditional measurement technology by lofting line long,station,cumulative error,etc.Through the application examples of the CORS system technology in the linear engineering land survey and boundary measurement,the results show that:the CORS system effectively covers a large distance,improves the accuracy of the lofting measurement,changes the traditional operation mode of the RTK measurement,simplifies the measurement process,saves the measurement time,and improves the production efficiency.This paper expounds the composition and advantages of CORS system,introduces the application cases of CORS system technology in land survey demarcation measurement,and statistics the accuracy of land survey demarcation measurement.
