CORS用户管理系统的研究与开发

Realization of CORS user management system

连续运行参考站系统CORS是在研究区域范围内,建立由若干个连续运行参考站、数据通信链路、数据中心和用户终端构成的局域网络,综合应用GNSS定位技术、计算机技术、数据通信和互联网(LAN/WAN)技术进行实时差分改正信息解算,实时地向不同类型、不同需求、不同层次的用户自动的提供经过检验的不同类型的GPS观测值(载波相位、伪距),各种改正数、状态信息,以及其他有关GPS服务项目的系统。本文以广泛应用的TrimbleCORS系统为例,分析了CORS系统的工作流程,详细介绍CORS系统的用户管理系统及其扩展应用(如坐标转换)的研究和开发,解决了CORS系统在商业应用阶段的相关问题。

Continuous Operational Reference System （CORS） consists of continuous operating GPS reference stations in the study area,data communication links,data center and user terminals with local network.It integrates GNSS positioning technology, computer technology, data communications and Internet （LAN/WAN） technology for distributing real-time differential correction information to the different groups,different needs,and different levels of users.It automatically provides tested different types of GPS observations （carrier phase,pseudo-distance）,various correction data,status information, as well as other services related to GPS systems.This paper,using Trimble CORS system as an example, analyzes the details of CORS system,workflow,user management system and its extended applications, such as coordinate conversion and system development to address the CORS system in the commercial application stage.
