摘　　要：以武汉城市圈CORS系统为基础,对CORS系统用户管理系统中地图加载、Web发布、分区域管理以及基于似大地水准面格网模型的实时精密正常高测量等关键技术进行了研究。目前,开发的用户管理系统和CORSPULS软件已成功应用于武汉城市圈CORS系统,不仅实现了实时计费、参数保密、分区管理,而且实现了系统数据的网络发布和精密正常高实时测量,进一步推动了CORS系统的广泛应用。This paper investigates and discusses the key technique within the the user management system such as map loading、web promulgating、managing user with authorizated area and real-time normal height precise positioning using the grid model of local quasi-geoid.The user management system and CORSPLUS software has been applied to Wuhan metropolis CORS system successfully,which not only achieve to real-time charging、keeping secrecy of transition parameter and managing user with authorizated area but also to realize the data promulgatd in network and normal height real-time precise positioning,and promote Wuhan metropolis CORS to be used in farther extensive domain.
