Median Orbit Repeatability (see table below): 7.0 cm

Analysis results from day 357 (week 1146) are not available at this time.
As such, statistics for day 356 in this week's Orbit Repeatability table below
are indicative of comparisons with the previous day (355) only.

Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated.  (For
geographical reasons, they may not have been used in any case.)
