Mean Orbit Repeatability (see table below): 22.6 cm

According to the file nanu1995.mes obtained from the IGS CBIS, PRN26 was
unusable on days 192 and 193 for maintenance (no maneuver).  Although data from 
this satellite were used in these days' analyses, we have elected to exclude
its solution from the corresponding sp3 orbit products.  Additionally, PRN23 
was unusable on day 195 for maintenance/repositioning.  Data from this 
satellite did not meet our initial convergence criteria on days 193-196, and 
have been excluded from our 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: Data from DAV1, METS, SPK1, TAIW excluded on day 190.
WARNING: Data from DAV1, MATE, PAMA, SANT, SPK1, TAIW excluded on day 191.
WARNING: PRN26 excluded from jpl0809[23].sp3, due to satellite maintenance.
WARNING: Data from DAV1, MATE, PAMA, SANT, SPK1, TAIW, UPAD excluded on day 192.
WARNING: Data from CHIL, CRFP, DAV1, FARB, LONG, MATE, MCM4, PAMA, PLTC, SANT,           SPK1, TAIW, TRAK, UPAD, VNDP, excluded on day 193.
WARNING: Data from CMP9, MCM4, PLTC, SANT, SPK1, TAIW, TROM, UPAD excluded on            day 194.
WARNING: Data from PRN23 excluded on days 193-196 due to a manuever.
WARNING: Data from CMP9, DAV1, EISL, GOLD, GUAM, MCM4, PLTC, SANT, SPK1, TAIW,           TROM excluded on day 195.
WARNING: Data from CMP9, DAV1, EISL, GOLD, GUAM, MONP, PAMA, SANT, SPK1, TAIW,           TRAK, TROM, ZIMM excluded on day 195.

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)
