Mean Orbit Repeatability (see table below): 18.4 cm

Although data from PRN29 were included on all days this week, this satellite
appears to be be mismodeled on days 157 and 158, as evidenced by atypically
high orbit repeatabilities on these two days.  We have elected to remove
solutions for this satellite from our corresponding sp3 products, jpl08563.sp3
and jpl08564.sp3.

Please note that beginning this week and for an indefinite period, orbit
repeatability results for the last day of the week (Saturday) only reflect
comparisons with the preceeding day (Friday).  Consequently, the last column
of the table is single-decimal precision.

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 ALGO) used as reference clock days 156-159.
WARNING: Data from DGAR, LAMA, MATE, USC1 excluded day 154.
WARNING: Data from DGAR, HOLP, OHIG excluded day 155.
WARNING: Data from BOGT, CHIL, DGAR, FORT, GOL2, HOLP, LAMA, NYAL, ONSA, QUIN, 
         STRL excluded day 156.
WARNING: Data from DGAR, FORT, HOLP, KELY, LAMA, MDVO, ONSA, STRL excluded day 
         157.
WARNING: Data from ALGO, MAS1, MDVO, ONSA, QUIN excluded day 158.
WARNING: Data from CHIL, DGAR, LBCH, MAS1, ONSA excluded day 159.
WARNING: Data from CHIL, DGAR, GOPE, LBCH, MAS1, POL2, QUIN excluded day 160.

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)
