摘　　要：基于410个国家级卫星导航定位基准站和多种软件系统,国家测绘地理信息局建成了国家广域实时精密定位服务系统。本文介绍了国家广域实时精密定位服务系统的业务流程、系统功能、系统特点、技术指标以及测试结果。终端定位测试表明,双频终端可达到分米级精度,单频终端为米级定位精度。Based on 410 national GNSS reference stations and various software systems, the National administration of Surveying, Mapping and Geoinformation has built a national wide-area real time precise positioning service system. This article introduces the business process, functions, features, technical indicators and test results of the system. Through the terminal positioning testing, the result shows that the dual-frequency terminal achieves the accuracy of decimeter level and the single-frequency terminal gets the meter level for positioning accuracy.
