介绍了多基站网络RTK技术建立的连续运行卫星定位服务综合系统(CORS)的基本构成及其优势,结合工程实例,阐述了SDCORS在水文地质调查中的应用情况、可行性以及达到的精度,着重说明了采取何种措施才能达到其所需精度。通过SDCORS在济西水源地水文地质调查中的应用,证明用该方法能够获得满足供水水文地质精度要求的测量成果,与常规方法相比具有方法可靠、测得的结果准确度高等优点,指出了测量时应该注意的问题。
This paper introduces the basic structure and advantages of continuous running satellite positioning service integrated system (CORS) established by RTK technology of multi-base station network, and expounds the application, feasibility and accuracy of SDCORS in hydrogeological investigation with engineering examples It shows what measures are taken to achieve the required accuracy. Through the application of SDCORS in the hydrogeological survey of Jixi water source, it is proved that this method can obtain the measurement results that meet the requirements of hydro-geological accuracy of water supply. Compared with the conventional method, it has the advantages of reliable method and high measured result accuracy. Should pay attention to the problem of measurement.
