Large deployable communication antennas operated in geostationary orbit require a stowage system to prevent unintended deployment during launch and to protect the deployment mechanism from vibration and shock loads induced by the launch environment. In addition, the stowage system maintains stable support for the deployable antenna during relocation to its target position after orbital insertion and enables the transition to the subsequent deployment phase. In this study, the dynamic characteristics of a stowage system designed for a large deployable antenna were analyzed through prefabrication dynamic analysis and ground deployment tests. A dynamic analysis model was established to simulate the deployment behavior under a zero-gravity environment. Using this model, the required specifications of torsion springs for deployment and the dynamic responses of the stowage system during the deployment process were analyzed. To verify the analytical results, ground deployment tests employing a gravity compensation device were conducted. The test results showed trends similar to those obtained from the analysis. This study provides a technical basis for future integrated analysis and testing of the stowage system combined with the deployable antenna.
