In order to predict the deployment time of deployable antenna and whether the deployment of the antenna meets the overall design requirements of the satellite, it is necessary to analyze the whole movement process of the antenna from folding to final unfolding. Before the ground simulation experiment of antenna deployment, the motion analysis of the deployment process is of great significance. In this paper, the deployment process of deployable antenna is analyzed by kinematics. Based on the theoretical model of a single antenna, the differential equation of motion of the deployment process is established. Based on ADAMS virtual prototyping technology, the prototype model of satellite and antenna is established, and the deployment process of the single antenna is simulated. The time-varying curves of the angle and moment during the deployment of the antenna are obtained by simulation. The changes of the position and velocity of the satellite mass center during the deployment of the antenna are studied. The influence of antenna deployment on the position and attitude of satellite body is analyzed.
