Mobile intelligent terminal differential locating system based on CORS enhancement

Abstract

The invention discloses a mobile intelligent terminal differential locating system based on CORS enhancement. The mobile intelligent terminal differential locating system comprises an intelligent mobile terminal, a CORS reference station network and a server, wherein the intelligent mobile terminal is provided with a data acquisition module and a first data transceiving and coding and decoding module connected to the data acquisition module, the server is provided with a second data transceiving and coding and decoding module and a data processing module and a differential resolving module which are connected to the second data transceiving and coding and decoding module, and the first data transceiving and coding and decoding module can conduct data interaction with the second data transceiving and coding and decoding module. The mobile intelligent terminal differential locating system has the obvious advantages that data processing and data resolving are both set in a server side, the data processing load of the intelligent mobile terminal is reduced, and the requirement of the intelligent mobile terminal for the hardware performance is also lowered; the problem that CORS servicecannot be accessed into the mobile terminal of a smartphone is solved, and the limit of expensive cost of a traditional measuring-type receiver is broken.

Description

technical field [0001] The invention relates to the technical field, in particular, it is a differential positioning system for mobile intelligent terminals based on CORS enhancement. Background technique [0002] The 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. Currently, the functions of GNSS positioning, timing and navigation have been greatly applied. However, the single GNSS positioning accuracy (about 10 meters) cannot meet the application of high-precision industries. [0003] At present, most provinces and cities in the country have built a complete Continuously Operation Reference System (CORS) infrastructure to provide positioning enhancement services for measurement-oriented professional users, and it has become one of the development hotspots of urban GNSS applica...
