Aiming at the modeling and simulation of modern micro-satellite multi-domain complex system, the multi-satellite modeling and simulation method based on Matlab / Simulink, ADAMS, ModelSim, Pro / E and STK are studied. Micro-satellite multi-domain modeling and simulation platform architecture, analysis of the coupling between the typical areas. The basic idea of establishing satellite dynamics simulation model based on ADAMS is proposed, and a multi-body satellite attitude dynamics ADAMS simulation model with rotating solar panels and reaction flywheel is completed. The interface middleware between software is designed and a multi-domain coupled simulation model of small satellite coupling is established, including control, mechanical, electronics and power supply. Finally, a large satellite attitude maneuver control mode is simulated. The simulation results verify the effectiveness of the proposed multi-domain modeling method and the feasibility of the simulation platform.
