Mean Orbit Repeatability (see table below): 17.4 cm

According to the file nanu1995.mes obtained from the IGS CBIS, PRN05 was
unusable on day 220 for maintenance/repositioning.  Data from this
satellite did not meet our initial convergence criteria on this day and the
following day as well, and have been excluded from our analyses accordingly.

Beginning day 221, we are excluding pseuodorange data from BOGT from our
analyses.

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: Data from PRN05 excluded on days 220 and 221 due to a manuever.
WARNING: Data from MAS1, MATE, MCM4, SPK1 excluded on day 218.
WARNING: Data from BRAN, FAIR, MATE, NALL, SPK1, WEST excluded on day 219.
WARNING: Data from BRAN, MCM4, SPK1, WETB excluded on day 220.
WARNING: Data from BRAN, DAV1, KOSG, LAMA, METS, SPK1, TROM excluded on day 221.
WARNING: Data from BRAN, CASA, DAV1, EISL, MATE, PIE1, SPK1 excluded on day 222.
WARNING: Data from CASA, DAV1, EISL, FAIR, MATE, NALL, SPK1, TROM, UPAD 
         excluded on day 223.
WARNING: Data from BRMU, CASA, EISL, MATE, NALL, SPK1 excluded on day 224.

In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column.  See IGS Report No. 1498 (jpl07827.sum)
