1+2模式的CORS多系统关键技术的探讨

Discussion of Key Technologies CORS multi-system 1+2 Mode

CORS(Continuously Operating Reference Stations,简称CORS)技术不仅集计算机网络管理技术、INTERNET技术、无线通讯技术和BD/GPS定位技术于一身,而且克服了常规RTK中要求基准站与流动站间距较近的缺陷,所以它将会是未来BD/GPS发展的一个方向。本文就目前着手的兼容GPS/BD的CORS建设的科技项目,对多模系统的CORS建设的关键技术和难点做了详细的分析。

Summary CORS（Continuously Operating Reference crisis ,CORS） technology is not only set computer network management technology ,INTERNET technology ,wireless communication technology and the BD/GPS positioning technology ,it overcomes the conventional RTK in base station and rover spacing is close ,so it will be a direction of the development of the BD/GPS in the future . In this paper ,the current set of compatible with GPS/BD CORS of the construction of the science and technology projects ,the CORS of multimode system of the construction of the key technology and difficult to do the detailed analysis .
