发布时间：2019-01-28 19:25
【摘要】：近几年来,随着一股连续运行卫星定位综合服务系统(Continuously Operating Reference Stations,英文缩写为CORS)的建设热潮,至今为止中国绝大多数的省份和城市均已建成各自的CORS系统,投入使用并取得了良好的效果。CORS系统现如今已然成为了我国地理空间参考框架的一项重要基础设施,它要求根据用户的不同需求向用户提供不同精度的三维导航和定位服务。然而CORS系统的基准站网的自身的稳定性对于保障CORS系统所分发数据的准确性和可靠性至关重要,是确保系统正常运行和提供优质服务的关键因素之一,也是系统运行维护过程中的一项重要内容。本文以云南省综合卫星定位服务系统(Yun Nan Continuous Operational Reference System,英文简称为YNCORS)的部分基准站为例,探索利用GAMIT/GLOBK软件研究和分析该CORS系统较大范围内各个基准站的稳定性,以保证CORS中心所提供的基准站站点坐标信息及发送的差分数据准确性的方案。最后根据研究结果得到CORS站点的稳定性结论,提出相应的解决方案。研究结果表明:该研究区域内所有基准站的自身稳定性均较为良好,同时证明该方法在大规模CORS站稳定性的研究中可行。
[Abstract]:In recent years, with the construction boom of (Continuously Operating Reference Stations, (CORS), the vast majority of provinces and cities in China have built their own CORS systems. CORS system has become an important infrastructure of geo-spatial reference framework in our country. It requires users to provide three-dimensional navigation and positioning services with different accuracy according to the different needs of users. However, the stability of the reference station network of CORS system is very important to ensure the accuracy and reliability of the data distributed by CORS system, and is one of the key factors to ensure the normal operation of the system and the provision of high-quality services. It is also an important part of the operation and maintenance of the system. This paper takes part of the reference station of Yunnan Integrated Satellite Positioning Service system (Yun Nan Continuous Operational Reference System,) as an example to study and analyze the stability of each reference station in the large range of the CORS system by using GAMIT/GLOBK software. In order to ensure the CORS center provided by the reference station point coordinate information and send the accuracy of the difference data scheme. Finally, according to the research results, the stability of the CORS site is obtained, and the corresponding solutions are proposed. The results show that the stability of all reference stations in the study area is good, and it is proved that this method is feasible in the study of the stability of large scale CORS stations.
