On-Orbit Assembly Technology of Large Space Antennas

With the development of space technologies, ultra-large deployable antenna will be assembled on orbit. The concept of the on-orbit assembly is discussed. The development status of the on-orbit assembly technology is summarized. The module design technology of the unit-split type space antenna is developed. According to the task requirement of the on-orbit assembly of the unit-split type space antenna, the schemes of the on-orbit assembly technology and ground laboratory experiments are investigated. The work can provide some useful references for developing China ’s on-orbit assembly technology of large space antenna.
