Abstract: Aneworbitdesignmethodisneededforpreciserevisitthegivengroundtrackpoints.Amethodofdesigningpreciserevisitof2givengroundtrackroundrepeatingorbitwasproposed.Therelationshipbetweenthesatellitegeocentricvectorandthegroundtrackgeocentricvectorwasanalyzed;theproblemwasconvertedtothecoincidenceproblemintheinertialcoordinatesystemofamotionvectorininertialcoordinatesystemandaconstantvectorinthemovingcoordinatesystem.Differenttargetfunctionswereconstructed,whileorbitelementswereobtainedbysearchingthezerosofthecorrespondingfunction.Calculationandsimulationresultsdemonstratetheeffectivenessoftheproposedapproach.
