CORS站在偏远海岛GNSS控制网布设中的应用

Application of CORS station in remote island GNSS control network deployment

随着全球导航卫星系统(GNSS)的发展尤其是各地连续运行参考站(CORS)基准站的不断建立与完善,充分利用CORS基准站来解决控制网的布设已经越来越普遍。本文以珠海市外伶仃岛GNSS控制网的布设为例,利用珠海本地的CORS基准站以及测区周边的香港CORS基准站共同组网,通过多级GNSS控制网的布设及解算实现了外伶仃岛GNSS控制系统的建立,并分析总结了CORS站在偏远海岛GNSS控制网布设中的应用。

With the development of global navigation satellite system(GNSS),especially the continuous establishment and improvement of continuously operating reference stations(CORS)reference stations in various places,it has become more and more common to make full use of CORS reference stations to solve the layout of control network.In this paper,it took the layout of the GNSS control network on Wailingding Island in Zhuhai City as an example,using the local CORS reference station in Zhuhai and the Hongkong CORS reference station around the survey area to form a network together.The establishment of the Wailingding Island GNSS control system was realized through the layout and calculation of the multi-level GNSS control network,and the application of the CORS station in the remote island GNSS control network layout was analyzed and summarized.
