中文摘要:
      CORS系统作为可完全代替传统单站差分测量的GNSS测量技术,具有可靠精度及更快速便捷的功能,得到广阔的应用。山洪灾害调查项目地域跨度大,调查内容点多面广,仅仅依靠传统测量难以按期顺利完成任务。特别是首级控制,若采用传统静态测量和水准测量,必将耗费大量时间和人力。通过构建区域CORS系统,真正实现单站作业,极大提高工作效率。项目建立的CORS系统运行稳定,实现测区全覆盖及全天候使用,并且精度校验符合项目技术要求,得到很好的应用。
英文摘要:
      As a GNSS measurement technology that can completely replace the traditional single-station differential measurement, the CORS system has reliable accuracy and more rapid and convenient functions, and has been widely used. The mountain torrent disaster investigation project has a large geographic span, and the content of the survey is wide-ranging. It is difficult to rely on traditional surveys to complete tasks smoothly and on schedule. Especially the first-level control, if using the traditional static measurement and leveling, will consume a lot of time and manpower. By building a regional CORS system, single-station operation and greatly increase work efficiency can be achieved. The CORS system established by the project runs stably, achieves full coverage of the survey area and is used throughout the day, and the accuracy check meets the technical requirements of the project and is well applied.
