Abstract: In order to meet the requirements of China's deep space exploration, space station construction, lunar exploration and other major aerospace projects for the rapid development of large space deployable antennas and other new satellite payload platforms, the micro-gravity environment simulation methods of space deployable antenna at home and abroad are reviewed. The working principle, advantages and disadvantages of typical gravity compensation methods, such as drop tower method, parabolic flight method, neutral buoyancy method, air floating method and suspension method, are analyzed respectively. The application and technical development in this field at home and abroad are reviewed. The technical characteristics and application scope of five micro-gravity simulation methods are analyzed and compared. Considering the needs of Chinese medium and long-term development plan for space science and technology, and from the aspects of large scale, high precision, diversification, generalization and high fidelity, the development trend and direction of micro-gravity environment simulation for space deployable antenna are proposed. The review provides a reference for the basic theoretical research and engineering application of large deployable antenna and micro-gravity environment simulation methods in China.
