The files that will be updated include: - all files in ftp://garner.ucsd.edu/pub/combinations/ (weekly orbits, repeatabilities, positions, sinex files, analysis summary files, earth orientation files, etc.) - all gpgga?.???.Z and sio* files located in ftp://garner.ucsd.edu/pub/products/ - all gpgga?.???.Z files located in ftp://garner.ucsd.edu/pub/gfiles/ This update should be completed within the next few days. After which, all the above-mentioned files (from GPS week 0576 to the present) will be in a uniform ITRF2000 reference frame. Orbit/analysis files produced by analysis centers other than SIO which are archived here at SOPAC will NOT be affected by this update. We will also be updating the position timeseries displayed on the SOPAC website to reflect ITRF2000 positions. A listing of the timeseries available for display is at: http://sopac.ucsd.edu/scripts/dbTimeseries.cgi Unfiltered timeseries will be available for all sites, including those which are regionally filtered. As a new service, we will begin to provide in ASCII format the position timeseries of all the permanent GPS stations analyzed at SOPAC. These will be published weekly on the SOPAC ftp archive at: ftp://garner.ucsd.edu/pub/timeseries Four tar files, each comprised of all available sites, may be downloaded from the timeseries directory: raw xyz, raw neu, unfiltered neu, and filtered neu. The (un)filtered neu tar files will also contain tables of all offsets and outliers. Best Regards, SOPAC Analysis Staff
