Abstract: Previousstudiesonspacesolarpowerstation(SSPS)havesimpleassumedgeostationaryorbit,whileitisnotthebestorbitforSSPS.Aneworbit,knownasthegeosynchronousLaplaceplanewasputforward,whichwassuperiortogeostationaryorbit.
Firstly,theorbitaldynamicsandtheperturbationswhichaffecttheorbitalmotionweremodeled,includingEarth′snonsphericalperturbation,LuniSolargravitationalperturbation,solarradiationpressureperturbationandmicrowavebeamingforceperturbation.Secondly,threeevaluationindexes,includingreceivedpower,orbitapplicabilityandspacesecurity,werepresentedtodiscusstheadvantagesoftheproposedLaplaceorbitratherthanthegeostationaryorbit.Finally,thelongtermnumericalsimulationwasprovided.AndtheresultshowsthattheSSPSworkinginthegeosynchronousLaplaceorbitcansave364534kilogramsoffuelwhichisusedfororbitmaintaincomparingtotheSSPSworkinginthegeostationaryorbitwiththesamereceivedpowerandmeetingthedemandofpowersupply.
