This study deals with the design of the marine antenna stabilization for an efficient 6 Degrees of Freedom(DOF) motion of a ship. Marine antenna must have abilities to target center and at the same time to stabilize the antenna dish in order to maintain its orientation toward the communication center. In order to achieve such requirements, structure stability and dynamics analysis to role to set up the simulation model. Prototype model designed and implemented into the DMU(Digital Mock Up) and MBD(Multi Body Dynamics) analysis method. Those simulation method has been carried out to stabilize the antenna under the ship motion. Simulation results show that the verification of structural stability better performance for marine antenna
