Weekly comparisons of orbits, clocks, tropospheres, coordinates, geocenter, scale, polar motion, and length of day are available at URL: http://igscb.jpl.nasa.gov/mail/report.html Click on the year of interest and then on the individual mail message. The most recent examples of each report are listed below. These reports span many years and provide a fairly robust set of comparison statistics.
