发布时间：2018-12-06 17:44
【摘要】：CORS-RTK是整个CORS系统中最重要的应用,是集计算机技术、网络技术、通讯技术、卫星定位技术于一体的实时差分定位技术。同传统RTK相比,它具有更高的定位精度、更远的作业范围、更高的可靠性以及更高的作业效率。该技术已经广泛应用于众多领域了。 目前,虽然多基站CORS系统是国内外学者的研究热点,但其高昂的建设成本让一些小规模的单位望而却步,而单基站CORS系统因其建设成本低、施工周期短、技术成熟、拓展方便等优势弥补了这一点,让其在中小城市和地区有了一定应用市场。 本文基于大连理工大学单基站CORS系统项目(LGCORS)展开研究,参与了整个系统的规划组建和性能测试,并最终归纳总结出一套适合单基站CORS系统建设和测试的方法。论文的主要研究成果如下： (1)学习国内外学者研究成果,总结了网络RTK基本原理与误差来源,介绍了当前流行的几种网络RTK的技术,为LGCORS系统的建设与测试奠定理论基础。 (2)详细介绍了LGCORS系统的基准站、通讯网络、数据中心的建设过程,总结一套单基站CORS系统建设方案。 (3)通过对网络RTK测试内容的研究分析,归纳出适合单基站CORS-RTK的测试方法和实施方案。 (4)结合大连市连续运行卫星定位服务系统(DLCORS)和部分大连市B级GPS点,完成了LGCORS系统内符合精度、外符合精度、时间可用性、空间可用性、差分定位均匀性、定位服务时效性及接收机兼容性的内容测试和评价分析。
[Abstract]:CORS-RTK is the most important application in the whole CORS system. It is a real-time differential positioning technology which integrates computer technology, network technology, communication technology and satellite positioning technology. Compared with traditional RTK, it has higher positioning accuracy, longer range of work, higher reliability and higher efficiency. This technology has been widely used in many fields. At present, although the multi-base station CORS system is the research hotspot of domestic and foreign scholars, but its high construction cost makes some small units prohibitive, while the single base station CORS system has low construction cost, short construction period and mature technology. Expansion and other advantages make up for this point, so that small and medium-sized cities and regions have a certain application market. Based on the research of (LGCORS), a single base station CORS system project of Dalian University of Technology, this paper takes part in the whole system planning and performance testing, and finally summarizes a set of methods suitable for the construction and testing of single base station CORS system. The main research results are as follows: (1) studying the research results of scholars at home and abroad, summarizing the basic principles and error sources of network RTK, introducing several popular technologies of network RTK. It lays a theoretical foundation for the construction and testing of LGCORS system. (2) the construction process of reference station, communication network and data center of LGCORS system is introduced in detail, and a set of construction scheme of CORS system for single base station is summarized. (3) through the research and analysis of network RTK test content, the test method and implementation scheme suitable for single base station CORS-RTK are concluded. (4) combined with Dalian continuous operation satellite positioning service system (DLCORS) and part of Dalian B-class GPS point, the accuracy of LGCORS system is completed, including the accuracy of coincidence, the accuracy of external coincidence, the availability of time, the availability of space and the uniformity of differential positioning. Content testing and evaluation of timeliness and receiver compatibility.
