The deployment of a modular truss antenna reflector is relied on the driven energy of the springs between the components of the structure. The deployment process is characterized by fast speed and large impact. In order to study the impact characteristics of antenna deployment on the boundary, the deployment dynamic analysis of a modular truss antenna reflector is carried out. The deployment impact experiment is performed to obtain the impact forces of the reflector on the boundary. The dynamic model of the modular truss reflector is modified according to the experiment results. The dynamic analysis of a satellite with an arm and a modular truss reflector is conducted by using the modified reflector model. The dynamic behavior of the satellite in orbit during the modular truss antenna reflector deployment is predicted.
