Abstract: Currently,themostcommonlyusedpatterninspacetargetobservationofspacebasedopticalsystemisnaturalintersectionmodewhichneedsalongcoverageperiod,andtheeffectofatmosphereradiationoftheearthonspacetargetobservationisnotestimated.Basedonthecharacteristicsofspacebasedplatformsonsunsynchronousorbit,severalobservationmodesforGEOtargetswereplannedandanalyzed,transformingtheeffectofatmosphereradiationofearthonspacetargetobservationintoacameraoffaxisangleconstraints,whichisvaluableforengineeringapplication.Theobservationefficiencywasevaluatedfromseveralaspectssuchasattitudemodes,coveragetimeandobservingarc.BoththeoreticalanalysisandsimulationresultsshowthattheregionalstaringmodehasabigadvantageforGEOobjectobservation.Thecoveragetimeislessthan24hours,whiletheattitudemodeiscomparativelysimple,andtheobservingarcislonger.
