摘　　要：针对CORS系统服务能力无法满足行业及大众应用领域快速增长的高精度位置服务需求的问题,该文提出了一种基于CORS的高精度位置服务云平台建设方法,通过将数据解算服务器与业务处理服务器进行分离,采用虚拟网格用户形式生成用于高精度定位的改正数或虚拟观测值产品,有效解决了高并发服务请求以及涉密数据安全性问题,在服务高精度测量用户的同时,提供面向开发者的各级精度位置服务接口,满足海量级、多场景、易接入的大众应用领域高精度位置服务需求。详细介绍了云平台构架设计、关键技术及具体实施方案,依托本文研究成果,湖南省已成功建设了基于HNCORS的面向大众应用领域的高精度位置服务云平台——问北位置,以期为各省级CORS高精度位置服务云平台的建设提供参考。In this paper,a cloud platform construction method of high precision location service based on CORS have been proposed to solve the rapidly growing demand for high-precision location services in the field of industry and mass applications.By separating the data processing server from the business processing server,it generated the error correction products or virtual observation of various levels through the users of the virtual grid which effectively solved the problems of high concurrency service requests and classified data secrecy issues.While serving high-precision measurement users,the platform provide developers with all levels of precision location service interface to meet the demand for high-precision location services on the mass class,multi-scenario and easy access.In addition,this paper details the design,key technologies and implementation plan of cloud platform architecture.Meanwhile,relying on the research results in this paper,Hunan Province has successfully built high-precision location based service cloud platform（www.sobds.com）based on HNCORS.This paper can provide reference for the construction of high-precision location based service cloud platform on provincial CORS networks.
