Median Orbit Repeatability (see table below): 10.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae, namely: BAKO BZRG GOPE HOFN INEG JOZE MATH MDVO PENC WTZT.

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 days 241-243 and 247.
WARNING: TID2 (not USNO) used as reference clock days 244 and 245.
WARNING: DRAO (not USNO) used as reference clock day 246.
WARNING: Data from JAB1, NOUM excluded day 241.
WARNING: Data from PRN15, EISL, JAB1, KOKB, TROM excluded day 242.
WARNING: Data from PRN02, PRN08, PRN15, JAB1, RIOP excluded day 243.
WARNING: Data from FORT, HERS excluded day 244.
WARNING: Data from BLYT, CASA, COSO, DHLG, JAB1, MAC1 excluded day 245.
WARNING: Data from BLYT, CASA, DHLG, HERS, JAB1, MAC1, TROM excluded day 246.
