摘要

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。%Basic structure and its advantages of the satellite positioning service system (CORS)established on the basis of network RTK technology have been introduced in this paper.Combing with project exam-ples,application,feasibility and accuracy approached of SDCORS in hydrogeological surveying have been pointed out,and the steps taken to make up the precision required have been introduced in emphsis. Through application of SDCORS in Jixi water source,it is proved that good measurement achievements which fit the precision demand can be gained by using this method.Comparing with conventional method, it is realiable and has higher accuracy.Problems which should be paid more attention in surveying have been pointed out as well.
