Taking the satellite borne electronic system of small satellite as researching object, the collaborative simulation of satellite borne electronic system was researched to overcome the limitation under the single simulation environment. Analysis of the principle of satellite borne electronic system collaborative simulation was carried out. The critical problem in collaborative simulation was also researched, and a satellite borne collaborative simulation scheme was proposed based on Matlab/Simulink and Modelsim. Aiming at PID control of small satellite large angle attitude maneuver, a collaborative simulation system was designed and the feasibility and practicability of satellite borne electronic system collaborative simulation was successfully verified. The collaborative simulation scheme discussed supplied an effective method to solve the problem of quick design and accurate verification of satellite borne electronic system of small satellite.
