摘　　要：简要概述基于GAMIT开发的大连地区地基GPS水汽自动处理系统的总体结构,设计思路,以及具体实现过程;还对系统反演的水汽资料进行精度检验以及误差分析,并介绍了系统反演水汽的质量控制方法,运行中常见故障的处理方法和日常业务中应用情况。初步应用结果表明:系统可用于解算地基GPS观测数据,获取高时空分辨率的水汽资料,用于天气分析和预报。系统具有解算精度高、运行稳定、自动化程度高等特点,具有很好的推广价值和业务使用价值。The construction of the GPS water vapor auto-processing system based on GAMIT, the system design concepts, and the specific implementation procedures are described. The accuracy check and error analysis of the GPS water vapor, the methods of the quality control and fault processing, and the application effectiveness in practical work are also discussed. The results show that the system can process the observation data from GPS stations to get atmospheric water vapor for weather analysis and forecasting. The system is highly automatic and easy to use, demonstrating great potential for operational use.
