Abstract

Abstract: General user terminal positioning accuracy can not meet the accuracy requirements of specific scenes. Based on the local CORS network and fusion data,this paper generates position corrections to correct the terminal position.After extensive testing of the development server and terminal software,the optimal scheme of grid generation and configuration is analyzed,and the real-time position differential external conformance test of virtual grid is performed.Experiments show that the virtual grid location difference can improve the accuracy of ordinary terminal positioning,and can provide the public with a plane RMS less than 3 m location service.

Key words: CORS, BDS/GPS, position difference, position service
