区域 CORS 数据自动化处理系统建设

摘要

At present ,CORS has entered a comprehensive application stage .Because of the large amount of data ,the method of manual management can not realize the real‐time monitoring of the reference station ,effective scientific data automation management ,and re‐liable high precision data processing results .So the data auto‐processing system were pro‐posed based on GAMIT/GLOBK and Bernese software ,and the overall structure and func‐tion of the system were designed .Based on the data of Shandong CORS for nearly three years ,the construction of regional CORS data automation processing and analysis system has realized ,the main functions includesthe automatic download of IGS data ,data warehouse management and maintenance ,data preprocessing and quality inspection ,data automation , and results visualization .The test shows that designed system can meet the high‐precise re‐quirements of auto‐processing CORS network .%目前区域CORS已进入全面应用阶段，由于其数据量大，以人工管理方式尚难以实现参考站的实时监测运行状态、有效科学的数据自动化管理和可靠的高精度数据处理结果解算。因此本文提出了基于GAMIT／GLOBK与Bernese软件的区域CORS数据自动化处理系统，设计了系统总体结构和功能设计。基于山东CORS近三年的数据，区域CORS数据自动化处理系统的建设实现了IGS数据的自动下载、CORS站观测数据的数据信息库管理和维护、数据预处理与质量检查、数据自动化解算、成果可视化输出等功能，算例测试表明，所建设的系统满足CORS网自动化数据处理的需求。
