基于CORS系统的虚拟基准站测量的应用研究

GPS技术已应用于静态、准动态、动态以及基础设施支撑下的实时动态测量中。GPS系统发展成多系统兼容的GNSS系统,区城CORS系统发展成全国统一的一个网,基础设施的完善促进了技术的进步。但在一些无法进行网络RTK作业地区的地铁、桥梁施工等高精度工程建设中,需要布设高精度控制网。如何利用现有的CORS系统资源,为这些地区的工程项目提供技术支持？本文针对该问题,利用已有的软硬件设施,开展了试验分析研究,提供了一套可行的解决方法。

The Application Research of Virtual Reference Station Surveying Basing on the CORS System

GPS technology has been applied to static, semi-dynamic, dynamic survey, even real-time dynamic survey under the infrastructure support. GPS systems have developed into multi-system compatible GNSS systems, regional CORS sys- tems have developed into a national Unified network, and the improvement of the infrastructure has promoted technologi- cal progress. But in some area, where the network RTK surveying can＇t be carried out, it is necessary to deploy high-pre- cision control network in some surveying projects of high precision engineering construction, such as subway, bridge con- struction. How do we provide technical support for ~he engineering projects in those areas by making use of the existing CORS system resources.9 In this paper, aiming at this problem, experiment analysis and research was carried out by mak- ing use of the existing software and hardware facilities, and a set of feasible solutions was provided.
