Velocity Field from Twenty-Two Years of Combined GPS Daily Coordinate Time Series Analysis

摘要

We uses survey mode (sGPS) and continuous GPS (cGPS) from Geospatial Information Agency, National Land Agency and Sumatran GPS Array (SUGAR) from 1993 - 2014 to derive new GPS velocities field in Indonesia region. In this study we quantify the velocities field from our GPS sites during this period. We reprocess and analyses our GPS data using the GAMIT/GLOBK 10.5 software suite. Our analysis reveals that the velocities field in Indonesia region has a distinctly pattern with the different direction and magnitude which represents the plates or blocks tectonic motion in Indonesia region. This information is useful for determines Indonesian deformation model to support the new Indonesian datum which called Sistem Referensi Geospasial Indonesia 2013 (Indonesian Geospatial Reference System 2013).
