Abstract: Thereislimitationtoconfirmingthereasonforthedatachangeofattitudesensorofspacecraftafterthetelemetrydatawerereceived,whichbringstheproblemthatthedatacan′tbeanalyzedintime.Tosolvethisproblem,anapproachwasproposedtostudytherangeofsolardisturbanceforattitudesensorbasedontwoangleparameterswhichreflectrelativepositionbetweenthesunandspacecraft.Therangeofsolardisturbanceforattitudesensorcouldgaininadvanceduetowellregulatedchangeofthetwoparameters.Consequently,whichcouldofferhelpfordatachangeandfailureanalysisofattitudesensor.Furthermore,itisbeneficialtothedesignofspacecraftattitudecontrolsystem,forexample,configurationandinstallationofattitudesensor.Inaddition,thefacultytorestrainsunlightofattitudesensorisvalidatedthroughtheway.Simulationresultsprovethevalidityofthealgorithm.
