Abstract
AUSPOS is Geoscience Australia's on-line static GPS positioning service, providing user access to a state-of-art analysis system via a simple web-interface. AUSPOS delivers ITRF2008, GDA94 and AHD coordinates to Australian users and ITRF2008 coordinates to international users by processing up to 7 days of user's GPS tracking data from up to 20 sites simultaneously. Like other GPS data processing systems, the internal coordinate uncertainty of AUSPOS solutions is typically too optimistic. In this paper, we report on a more realistic uncertainty estimation method for AUSPOS. Test results using this method shows that uncertainties of AUSPOS solutions vary from several millimetres to several centimetres, with respect to ITRF2008, depending on the duration of data sets and their global location.
