A solution of mathematics simulation for space communication links connecting with hardware can be carried out to support real-time simulation. This paper analyzes the merits and shortcomings between mathematics simulation of space communication chain and semi-physical simulation, and designs both circuit-opened and circuit-closed space communication chain methods for the semi-physical simulation. The paper takes the characteristic simulation of space microwave chain transmission and the evaluation of communication quality of space microwave chain as key researches. The results of simulation on satellite communication links show that the performance of platform is effective and practical.
