SYCORS参考站选址建设分析研究 　　摘要：介绍了沈阳市连续运行参考站网络是辽宁省首个大型GPS连续运行参考站系统（SYCORS），该系统由1个控制中心和7个参考站构成，覆盖沈阳全市域。同时就沈阳市GPS连续运行参考站系统（SYCORS）参考站选址的分布设计、选址原则、参考站的建设等进行了详细的说明。在选址过程中，利用场强仪监测和实测数据分析的方法，充分保障了参考站的数据质量，严密了参考站站址选择方法。SYCORS是将现代卫星定位、计算机网络、数字通讯等技术进行多方位、高深度集成的结晶，它作为“数字城市”地理空间基础框架的子项目，也是沈阳市“空间数据基础设施”的最为重要的组成部分。对于其他城市建立CORS提供了宝贵的经验。该系统的建成将实现沈阳市现代化、高精度、高动态、统一的测绘基准和测绘系统，从而满足沈阳市国民经济和社会持续稳定的发展有着深远的意义。 　　关键词：SYCORS；基线；观测墩；观测室 　　Abstract: the article introduces the continuous operation of shenyang station network is a reference in liaoning province first large GPS continuous operation reference station system (SYCORS), this system consists of a control center and seven reference stand, which covers the whole xiamen city of shenyang. At the same time GPS continuous operation of reference station system (SYCORS) reference stood the location of the distribution, the site principle, design of construction reference stood a detailed description. In site selection process, use the field monitoring instrument and real data analysis method, to fully guarantee the reference of data quality stand, closely reference station hail selection method. SYCORS is modern satellite positioning, computer network, digital communications technology is analyzed, high deep integration crystallization, it as a digital city geographical space since the basic frame, and shenyang spatial data infrastructure of the most important part. For other cities build CORS provided valuable experience. The system will achieve the completion of shenyang modernization, high precision, high dynamic, unity of surveying and mapping of benchmark and mapping system, shenyang and meet the national economic and social development has a stable of profound significance. 　　Key words: SYCORS; Baseline; Observation pier; station 　　 　　 　　???图分类号： P185.11 文献标识码：A 文章编号： 　　连续运行参考站网络(Continuously Operating Reference Stations， CORS)是利用全球导航卫星系统（Global Navigation Satellite System，GNSS）技术，在某个城市、某地区建立永久性的连续运行参考站、系统控制和数据处理中心（简称控制中心或中心），利用计算机、数据
