Median Orbit Repeatability (see table below): 11.0 cm

According to the file nanu1999.mes obtained from the IGS CBIS, PRN01 was
unusable on day 030.  Data from this satellite did not meet our initial
orbit convergence criteria on this or the following day (031) and have
been excluded from these days' analyses accordingly.

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.)

WARNING: PIE1 (not USNO) used as reference clock day 037.
WARNING: Data from PRN18 excluded the entire GPS week 995.
WARNING: Data from PRN01 excluded day 031.
WARNING: Data from PRN05 excluded day 033.
WARNING: Data from COCO, GLSV, MATH, NICO, TID2 excluded day 031.
