| Abstract: | 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. |
