A review of module adjustment for space on-orbit assembled antenna

Space deployable antennas are extensively utilized in space-based communication, deep space exploration, and earth observation. As the demands for capacity and data transmission rates in human space-based communication continue to rise, the requirement for larger antenna apertures becomes increasingly critical. Traditional single-deployable structures are insufficient to meet these aperture requirements. On-orbit assembled antennas present a viable solution to the challenges associated with folding, transportation, and deployment of large structures, thereby overcoming the aperture limitations inherent in conventional designs. This innovation is particularly pertinent for large aperture space antennas required in space-based communication and related fields. The ability to adjust modules is a foundational aspect of realizing on-orbit assembly antennas. This paper provides a comprehensive review of the current research on module adjustment in space on-orbit assembly antennas. Initially, the existing research landscape of space on-orbit assembly antennas is outlined. Subsequently, the progress made in module adjustment is categorized into two main approaches: inter-module adjustment and self-adjustment of modules. The paper also examines various actuators that can serve as critical components in the design of module adjustment systems. Building upon this analysis, key technologies essential for effective module adjustment are summarized, and future development trends in this area are proposed.
