摘要

摘要本研究利用视同漫游者分析方法,对泰国GNSS连续运行参考站(CORS)用于基于网络的实时运动学(NRTK)定位的性能进行了评估。选择了50个具有不同网络几何形状的CORS作为漫游车。结果表明,对于平均长度为54公里的三角形,固定解决方案的性能最高,为79.9%,而对于长度为93公里的精度为分米级别的三角形,性能最低,为29.9%。这些初步的探索表明,减少边长可以提高探测车的固定求解效率和定位精度。偶尔会发生米级错误,可能与互联网不稳定有关。关键词:视景漫游者分析vrsnrtkgnssrtklib致谢作者感谢泰国皇家测量部(RTSD)提供了所有必要的数据和设备支持。我们感谢泰国GNSS和空间天气信息数据中心主任Pornchai Supnithi教授为泰国提供总电子含量(TEC)数据。putttipol Dumrongchai,美国俄亥俄州立大学大地测量科学与测量专业博士学位。他是泰国清迈大学工程学院土木工程系副教授。主要研究方向为大地水准面测定、GNSS测量、CORS系统。第一作者对研究论文的主要贡献包括设计实验方法,分析和讨论结果,以及撰写和组织论文。Nantawat Kongkratock持有朱拉隆功大学(Chulalongkorn University) GNSS测量硕士学位。他现在在泰国曼谷的皇家泰国测量部工作。在本文中,他收集了所有相关数据,进行了计算,并进行了数据分析和讨论。Chalermchon Satirapod博士毕业于澳大利亚新南威尔士大学(UNSW) GNSS测量专业。他是泰国曼谷朱拉隆功大学工程学院测量工程系的全职教授。他的研究兴趣是新的全球导航卫星系统数据处理技术和质量保证的全球导航卫星系统测量的一系列静态和运动学应用。在本研究中,他参与了实验方法的设计,提出了重要的意见和宝贵的建议,并始终作为通讯作者。他获得泰国清迈大学土木工程硕士学位。他目前是清迈大学工程学院土木工程系土木工程博士研究生。主要研究方向为本地大地水准面测定和GNSS测量。在本文中,他从CORS中准备了额外的GNSS数据,并使用RTKLIB进行了进一步的实验。

Performance assessment of continuously operating reference stations using the deemed rover analysis approach with NRTK GNSS technique in Thailand
AbstractThe study initiated an evaluation of the GNSS continuously operating reference stations (CORS) performance for Network-based Real-Time Kinematic (NRTK) positioning in Thailand, using the deemed rover analysis approach. Fifty CORS were selected as rovers with varying network geometries. Results indicated the highest performance, 79.9% of fixed solutions, for an average triangle side length of 54 km, while the lowest performance, 29.9%, was observed for a 93 km length with accuracies at a decimetre level. These initial explorations suggest that reducing side lengths enhances fixed solution efficiency and positioning accuracy at rovers. Occasional metre-level errors occurred, potentially linked to Internet instability.Keywords: Deemed rover analysisVRSNRTKGNSSRTKLIB AcknowledgmentsThe authors would like to express their gratitude to the Royal Thai Survey Department (RTSD) for providing all the necessary data and equipment support.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
