| Abstract: | Because of its inherent characteristics, space communications link raises new requirements and challenges on the QoS (Quality of Services) of space communications. This paper suggests architecture for the emulation of space communication system and achieves its implementation with STK (Satellite Toolkit). Meanwhile, we develop QoS performance measurement software for space communications system and analyze the QoS performance of proposed architecture. |
