摘　　要：The DFH-3B platform is a geosynchronous common satellite platform whose capability is between that of the current DFH-3 and DFH-4 platforms.The DFH-3B platform makes comprehensive use of the most internationally advanced space technologies such as Lithium-ion battery,integrated electronics,high efficiency thermal control and electric propulsion.The development of the platform will meet China's imminent demands for the development of satellites for civil communications,and greatly enhance China's competitiveness in the international communications satellite market.The DFH-3B platform is a geo- synchronous common satellite platform whose capability is between that of the current DFH-3 and DFH-4 platforms. The DFH-3B platform makes comprehensive use of the most internationally advanced space technologies such as Lithium-ion battery, integrated electronics, high efficiency thermal control and electric propulsion. The development of the platform will meet China＇s imminent demands for the development of satellites for civil communications, and greatly enhance China＇s competitiveness in the international communications satellite market. The greatest characteristics of the DFH-3B platform is the use of electric propulsion to fulfill the southnorth station-keeping during the 15-year lifetime of the satellite, which is also the core technology to achieve a performance leap from other platforms.
