摘要
港珠澳大桥GNSS连续运行参考站系统是国内首个独立的基于VRS的工程CORS系统。结合工程条件与建设需求,本文分析了该系统建设的特点和技术难点,介绍了系统组成、总体结构和基本功能,以及参考站联测及精化大地水准面的应用情况。系统实时定位精度测试分析结果表明:基于VRS的网络RTK的定位精度平面优于±2cm,高程优于±3cm,实现了系统的建设目标。
The GNSS continuously operating reference stations system of Hong Kong-Zhuhai-Macao Bridge is the first independent VRS-based engineering CORS in China. Combining with the engineering environment and project needs, the construction characteris- tics and technical difficulties were analyzed in the paper. Therefore, the composition, overall structure and essential functions of the CORS, as well as the reference station connecting surveying and the application of the precise quasigeoid, were discussed. Through the analytical results of the real-time kinematic（RTK） satellite navigation of the system, it was showed that the presision of the GNSS net- work RTK based on VRS excels ± 2 cm in horizontal direction and ±3 cm in vertical direction, by which the construcrion goal of the system was realized.
