Aiming at modeling and simulation, the study of the method of multi-domain modeling and simulation for modern micro-satellites were focused on, based on simulation software interfaces such as Matlab/Simulink, ADAMS, ModelSim, Pro/E and STK. The framework of multi-domain modeling and simulation platform for micro-satellites based on multi-simulation software was proposed, and the coupling models between typical domains were analyzed. The basic idea for the establishment of satellite dynamics simulation model based on ADAMS was formulated, a satellite attitude dynamics simulation model based on ADAMS was completed, which contains the dynamics models of uniaxial rotating solar panel and reaction flywheel. The interfaces between software were solved, and then the simulation model for the strong coupling relationships among the control, mechanics, electronics, and power subsystems ofmicro-satellites was established. Finally, the control mode of a large angle attitude maneuver was simulated, and the simulation results have proved the efficiency of the multi-domain modeling method and the feasibility of the simulation platform.
