　　摘要
　　卫星定位连续运行参考站网相关技术的应用与研究，目前是测绘界研究的热点之一，国内外各类 CORS 正相继建立。经历多年的理论研究和具体实践，其工程水平和技术水平相继成熟，积累了一定的核心算法和服务模式，已经到了从整体上对其进一步研究和集成优化的阶段。建设 CORS 的服务体系是一个复杂的系统化工程，涵盖了 CORS 从数据采集到服务应用整个流程。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，主要研究内容
　　和创新点如下：
　　1）在立足当前研究现状和现有 CORS 建设的基础上，讨论了 CORS 的概念和较全面的分类；对 CORS 基础设施完备性进行了探讨，对 CORS 各组成部分及其功能定位做了划分和界定；较详细地分析了各子系统的功能和设备组成，建立了完善、实用且有利于扩展的拓扑结构；分析了 CORS 系统中最为核心的两种服务形式（实时定位服务与精密事后服务），分别阐述了其业务流程和数据流程；对 CORS 的技术指标，按覆盖范围、服务领域、系统精度、服务方式、可用性、完好性和兼容性等方面进行了表述。
　　2）对 CORS 相关软件的研制现状进行了分析和总结，对 CORS 的业务流程和数据流程进行了建模，提出了较完备的 CORS 分布式软件体系结构、层次模型、部署方式。基于 CORS中间件平台（CORS-MW），对基准站软件（CORS-RSS）、系统管理软件（CORS-SMC）、数据计算软件（CORS-DOT）、用户服务软件（CORS-USS）、事后定位服务软件（CORS-WEB）和用户应用软件（CORS-UAS）等 6 个软件进行了自主设计，并用 UML 图例对各个软件的部件、类和核心交互流程进行了较详细的阐述。
　　3）对 CORS 相关的业务数据、工况数据等进行了分析和汇总，提出并采用了基于实时数据的存储和管理方式，设计了基准站数据库、业务数据库和服务数据库等三类数据库，并阐述了它们之间的数据同步关系，建立了较合理的数据库逻辑模型和物理模型。
　　4）针对 CORS 事后定位服务，制定了软件设计和开发策略，将 CORS-WEB 划分为在线数据服务系统（CORS-ODS）和在线定位服务系统（CORS-OPS）两部分。对两者的基本功能分别进行了较细致的分析，提出了技术集成方案和系统设计方案，开发了原型系统。
　　本文提出的 CORS 系统架构，从完备性、集成性、可扩展性、安全性方面进行了较细致的研究，并给出了较合理的方案，对 CORS 相关工程建设有一定的借鉴意义；本文在软件体系架构方面的设计成果和实践，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一系列问题，具有一定的实用价值。
