面向CORS的精密定位服务中间件平台的设计

Design of CORS Oriented Middleware Platform of Precision Positiomng Service

目前，卫星定位连续运行参考站网相关技术的应用与研究是测绘界研究的热点之一，国内外各类CORS正相继建立。本文针对CORS服务体系的数据共享和服务共享问题，从软件工程角度对CORS的数据采集、处理、计算、分发、服务等方面作了进一步梳理，建立了较完备的网络体系和软件体系模型，提供了一个较完备的面向CORS的中间件平台设计思路。本文的设计成果和实践，可有效地改善当前CORS领域软件开发现状中软件和研究成果保密、软件功能单一、无统一的开发标准和架构模型等问题，具有一定的实用价值。

At present , the applications and research for Continuously Operating Reference Stations （CORS） technology is one hot spots of geodesy , each kind of CORS has been establised one after another in domestic and abroad. In this paper, the problem for data and service sharing is discussed in view of the software engineering. Many aspects of CORS, such as acquisition, processing, computation, distribution, service and so on, are sorted out one by one. And then, the complete CORS distributional software architecture, the hierarchical model and the deployment diagram are proposed. The results of design and related practice to software architecture presented by the paper have certain practical value. It can give an answer to some series of questions in CORS software field, such as software and research results confidential, the sole of function, the absence of a unified framework for the development and construction and so on.
