Abstract: Tocalibratetheorientationpositionofthesatelliteorbitbythetemperaturesensors，theordinaryKrigingmethodwidelyusedingeo-statisticswasappliedintothetemperatureestimationprocessofthesatellite.Arapidthermaldeformationanalysismethodwasdevelopedbasedonthestatisticmethods.Basedonasmallamountoftemperaturesensors，estimationofthetemperaturefieldwascarriedout.Then，thetemperaturefieldwasusedforthefiniteelementanalysistoaccomplishthethermaldeformationanalysis.Differencesbetweentheanalyticalandtheexperimentalresultsofthedeformationofthepayloadarearound1′，whichconfirmsthatthemethodcanbeusedtoobtainthevariationofopticalaxisofthepayload.Furthermore，comparedtothethermophysicalmethod，theworkperiodcanbereducedbyseveraldays.Thisworkprovidesguidanceforrapidthermaldeformationanalysisofon-orbitsatellites.
