Design and implementation of virtual managed user machine system based on "Beidou-I"

For "Beidou-I" satellite navigation and positioning system,there is limited capacity to monitoring and cost problems,the authors put forward and designed a virtual managed user machine system.This paper introduced the functions and structure design of the system,focused on analyzing the design and implementation of the key components such as the Beidou shared database,the data unified processing module and so on.As the communication information sending and receiving,for example,it described the system workflow.Finally,the experiments and applications of the system proved its feasibility and rationality.
