Aiming at modeling and simulation, the study of improving the performance of the method of multi-domain based on multiple interfaces of satellites by the IOCP technology were focused on. The satellite's attitude and orbit controlling simulation platform was build, with the server based on the IOCP technology build, and the designation problem of interfaces between different software solved, while the model of the satellite build, by using software , such as MATLAB / Simulink, ADAMS, Pro/E, STK and VS. Finally, the model of satellite's attitude maneuver was simulated, and the result proved the efficiency of the method of multi-domain based on multiple interfaces of satellites improved by the IOCP technology.
