In this paper, the zero-gravity unloading scheme and the design scheme of the zero-gravity unloading process equipment are proposed for the three-overlapping antennas of a communication satellite. Due to the particularity of the structure, test state and unloading state of the communication satellite antenna, the zero-gravity unloading simulation process equipment commonly used at present cannot meet the test requirements. Based on the analysis of the requirements of zero-gravity deployment test and the process of the three-overlapping antennas zero-gravity unloading, a solution to meet the test requirements is proposed. System performance tests verified the effectiveness of the zero-gravity unloading system.
