Research of Space Station Data System structure design

Characteristics of the space station and its data system are introduced in this paper. Application of Advanced Orbiting System (AOS) in Space Station Data System (SSDS) is analyzed and the design thought of the data system is given. Then design of the system structure is presented. And key parts of the system, high-speed link controller and channel multiplexer/demultiplexer, are analyzed and designed in detail. High-speed link controller can achieve the bit stream service of the data with speed of 220 Mbps. Six path dynamic data can be reliably multiplexed and demultiplexed by multiplexer and demultiplexer, and its data rate is up to 280 Mbps.
