Abstract

The Indonesian Permanent GPS Station Network (IPGSN) is a network of continuously operating GPS reference stations. The primary purpose of the IPGSN is to maintain a geodetic reference frame over Indonesia region by making publicly available the precise coordinates of all the IPGSN stations in International Terrestrial Reference Frame (ITRF) and World Geodetic System 1984 (WGS84) reference ellipsoid. In recent development of processing strategies and algorithms, such as further improvements in models of solid Earth tide, ocean tide loading, absolute the phase center variation, tropospheric mapping functions and atmospheric pressure loading have lead to incremental improvements in geodetic GPS point positioning accuracy. In this study we evaluate the geodetic station coordinates accuracy and associated time series repeatability of a local network like IPGSN, with those models applied in GPS analysis strategies.
