摘要：This paper analyzes the character and performance of the synthesized test bed on ground of small satellites. By studying several small satellite systems, the hardware and software architectures of flexible test bed are presented. The communication request/reply relations as well as other communication parameter's dynamic configuration, TM data format's dynamic description, TM signal's automatic analysis and presents, on-board internal as well as communication monitor between satellite and ground on satellite host computer and each kind of lower computer functional simulation and so on, provides an general test simulated platform for each constituent's development on-board, has built a closed loop simulation testing environment for the entire satellite jointing debugging. Dynamic configuring each kind of parameter is the concrete manifestation of the test platform flexible thought, the flexible test bed's realization establishes an general test simulated platform for the smallsat development, has made up the traditional special-purpose test system's insufficiency. The design and corresponding implementation are proven very effectively on the development of three small satellite systems.
