Abstract:    In order to achieve the application of GNSS data sharing, allow more users to make full use of existing data resources, break the constraints of data scarcity, reduce duplication oflabor and other costs, provide an effective and visual data sharing service byinteractive portal, we need to design an implementation of data sharing service platform.Thispaperanalyzes the user's need for data sharing platform interoperability, based on the SSM framework design of the B／S (browser／server) model GNSS application data sharing platform, for GNSS applications users provide staticand dynamic data downloads.The architecture of the data sharing platform is composed of data acquisition layer,data storage layer, data analysis layer, processing layer and data sharing layer.The loose coupling of various hierarchical features a clear mechanism, and has good scalability.
