Abstract：WiththewidespreadapplicationofGPStechnologyinmodernlife，itisparticularlyimportanttoaccurately estimatetheconfidenceofGPSdataandachievehigh-qualitytrajectoryfiting.Thisresearchproposesamethodthatcombines GPSconfidenceevaluationwithdynamictrajectoryfiting.Trough hierarchical processng，directioncoectionandpolyomial fitingofGPSdatatheacuracyandrobustnessoftrajectoryfitingaresignificantlyimproved.Researchshowsthatthismethod canefectivelyreducepositioningerrorscausedbyvehiclestandstll，signalolusionandmultipathefectsincomplex environments.Inthe experiment，theroot-mean-square error（RMSE）of the fiting curve was reduced by 15% ，while the accuracy of trajectory matching was increased from 91.1% to 93.02% ，reflecting the superiority of this method in terms of accuracyandcalculationeficiency.Thisachievementprovidesstrongsupprtforappicationsinfieldssuchasinteligent transportation，autonomous driving and high-precision map construction.
