Abstract: Consideringtheproblemsoftheelectricalpropertiesareaffectedbythermaldeformationofsatellitecontrolantenna,apredictionmethodfortheextremetemperatureconditionsofsatellitecontrolantennawaspresented.Inthemethod,thesolarradiationwascombinedwiththeparabolicantennapanelequationtocalculatethesolardirectpointtrajectoryofsatellitecontrolantennas,anddeterminedtheantennapositionparameters.Thevariousenvironmentalfactorsofantennaweretakenintoaccountandtheextremeconditionsoftheantennawerepredicted.Comparedwiththesimulationandexperimentalresults,thereliabilityofthedirectsunlightpointtrajectorycalculationmethodandthepredictionmethodsoftheextremetemperatureconditionsareverified.
