GPSRTK技术及其在道路工程测量中的应用 Abstract GPSRTK(Real-TimeKinematic)technologyisahigh-precisionpositioningtechnologywhichhasbecomeverypopularinrecentyears,especiallyinthefieldofroadengineeringsurveying.TheaccuracyofthistechnologyissignificantlyhigherthantraditionalGPSsurveying,makingitanimportanttoolforachievinggreateraccuracyandprecisioninroadconstructionandplanning.ThispaperwillexplorethebasicprinciplesofGPSRTKtechnologyanditsapplicationinroadengineeringsurveying. Introduction Roadengineeringsurveyingplaysanimportantroleinthedesign,construction,maintenance,andrepairofroads.Thesurveyingprocessinvolvesaseriesofmeasurementsthatareusedtodeterminethelocation,elevation,andorientationofvariouspointsonasite.Inthepast,traditionalsurveyingtechniqueswereused,whichcouldbetime-consumingandoftenlackedaccuracy.However,withthedevelopmentofmoderntechnology,GPSRTKhasbecomeanincreasinglypopularmethodforsurveyinginroadengineering.
