The monitoring of the settlement of the Ponre-Ponre dam aims to determine the condition of the dam's body stillin the condition as planned or not. To find out the settlement of the weir body requires tools and methods with highaccuracy and precision. This study aims to compare the accuracy and precision of the two GNSS (Global NavigationSatellite System) survey methods and use a survey method with higher accuracy and precision values. The benefit of thisresearch is to complete the data series of dam settlement with the latest measurement data. This study compared theresults of the static survey method measurements with the RTK survey of the parameters of the value of accuracy andprecision values. The method with a smaller value of accuracy and precision is used to measure the decrease in the bodyof the dam. The results of this study indicate that the static survey method gives an accuracy value and a smaller orderprecision value than the RTK survey method. Decreasing body dam in the last four years (2015 - 2018) has decreased by4,483 cm every year.
