Problems solved by technology

Therefore, in some provinces and cities, there are multiple sets of foundation enhancement service software coexisting and operating independently. Different software corresponds to different login ports, and users are more blind when using them. Resources cannot be allocated reasonably, which directly affects the efficiency of user positioning
[0004] In addition, some foreign software (such as Tianbao GPSNET software in the United States) has restrictions on the number of user visits. When one of the software visits exceeds the limit, subsequent users cannot be assigned to othe

Abstract

The invention discloses a GNSS ground base station enhancement service management system. The system includes a GNSS base station network, a data processing center, a broadcasting service management module and a user terminal. The GNSS base station network is composed of GNSS base stations distributed uniformly in an area and is used for collecting satellite navigation signals continuously. The data processing center includes a GPS single mode data processing module and a BDS/GPS dual mode data processing module and is used for calculating a differential correction number. The broadcasting service management module performs data processing module selection and data forwarding according to a requested data source type and a current load condition. The user terminal sends information and acquires the differential correction number, and implements high precision positioning through combination of observation data of the user terminal itself. The system has distinctive effects that integrated and balanced service of multiple ground base station enhancement service software is realized and online information management of accounts by system administrators and unit administrators is realized.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a GNSS ground-based enhanced service management system. Background technique [0002] Global Navigation Satellite System (GNSS, Global Navigation Satellite System) mainly includes four major satellite systems: GPS of the United States, GLANESS of Russia, GALILEO of the European Union and Beidou Satellite Navigation System of China. At present, GNSS positioning, timing, and navigation functions have been widely used, but the single GNSS positioning accuracy (about 10 meters) cannot meet the applications of high-precision industries, such as topographic mapping, precision engineering measurement, deformation monitoring and other fields. The ground-based augmentation system is mainly composed of GNSS satellites, satellite navigation and positioning reference stations (hereinafter referred to as GNSS reference stations), data processing centers, data broadcasting s...
