| Abstract: | Reliable deployment of large spacecraft antenna is a key for the success of space mis- sion. The failures of large satellite antenna deployment in a part of scientific, commercial and mil- itary satellites from 1974 to 2011 are surveyed and analyzed. The failure causes and modes of the satellite antenna deployment are reviewed, and the emergency operations and the improvement schemes of deployment are summarized. According to the characters of the large deployable satel- lite antenna, some suggestions such as enhancing their anti-impact ability, verifying the antenna deployment through sufficient experiments and making prior researches on the recovery tech- niques are proposed to increase the deployment reliability of the large antenna. |
