Abstract: TooptimizetheequipmentconfigurationschemeofGEOsatelliteplatform,aLithiumionbatteryconfigurationoutsidetheeast/westpanelwasproposed.Thefeasibilityoftheschemeanditsinfluenceonsatelliteplatformwereanalyzedfromseveralaspects,especiallyinstructuraldesign,thermaldesignaswellasdevelopmentprocessofsatelliteplatform.Takingthe135A·hLithiumionbatteryasanexample,theanalysisresultsofthermalcontroldesignshowthatthenewconfigurationofLithiumionbatteryhasmoreadvantagescomparedtoitsconfigurationinsidethesouth/northpanel.Thenewconfigurationnotonlysavesmorelayoutspaceforlotsofequipmentinsidethemoduleofsatelliteplatform,butalsooptimizesthedevelopmentprocessofthesatellite.Furthermore,themechanicalandthermalperformancesofthemountingpanelarealsoimproved.Forinstance,theheatingpowerandheatrejectionareaaredecreasedby70%.Significantsavingsofthedesignresourcesareobtained.Therefore,theproposedconfigurationisaneffectiveapproachtoenhancethesystemperformanceofsatelliteplatform.
