Abstrak/Abstract Monitoring Borobudur temple’s position is an attempt to maintain one of the world’s heritage. Measurement using GPS in order to observe Borobudur temple’s stability had been done at 12 points in 2002, 2003, and 2012, using GPS Analysis and referring to ITRF2000 to analyze the horizontal movement. The difference resulted from the use of ITRF in GPS data processing has an effect of the accuracy in analysis of the GPS control points. The purpose of this research is to measure the position estimation, velocity, and the movement direction of the GPS control points based on data 2003 and 2012 referring to ITRF 2008. The process has been gone through regional and local processing. The coordinates acquired from GAMIT/GLOBK local processing is compared with coordinates based on ITRF2000 which has been transformed to ITRF2008. Point displacement analysis are based on the coordinates and data results from 2003 and 2012. This study stated that the difference in position and its accuracy in both regional and local processing indicates that all the transformed values from ITRF 2000 to ITRF 2008 are still within the range of two sigma level of the GAMIT and GLOBK results referred to ITRF2008. Furthermore, the mean of horizontal displacement value for the period 2003 and 2012 was 261 mm in the southeast (SE) direction which similar to the use of ITRF2000 in previous study. In general, the Borobudur temple network adjustment referring to the ITRF 2008 was more accurate compared to the previous studies which referred to ITRF2000.
