Abstract: Withthedevelopmentofmobilecommunicationtechnology,thelargedeployableparabolicmeshreflectorsarewildlyusedto improve the antennagain.Consideringthelargeinertia,long-perioddeployment,andlowstiffnessproperties,theseantennaehaveagreatinfluence on thedynamicsandcontrolofthesatellites.Firstly,thestructuralcharacteristicsanditsinfluencesonthe dynamicandcontrolof thewhole-satellitewereintroducedforthelargemeshdeployableantenna.Secondly,thedynamicand controlproblemswerediscussed,such asdynamicmodelingofthedeployedantenna,verificationmethodofthedeployed dynamic model,multi-bodydynamicsofthe deploying antenna,deploying-processattitudecontrol,andpointingcontroloftheantenna,and soon.Finally,theprospectsofthedynamicsand controlofthesatellitewithlargedeployableantennawerepresented.
