Median Orbit Repeatability (see table below): 13.0 cm
                           (excluding deweighted satellites)

We continue to deweight data from PRN10 this week.  Additionally, PRN14
appears mismodeled on days 362 and 363.  Solutions for this satellite
have been removed from the corresponding orbit products (jpl08855.sp3
and jpl08856.sp3).

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 PRN10 deweighted for the entire GPS week 855.
WARNING: Data from COCO excluded day 357.
WARNING: Data from CHUR, NYAL excluded day 358.
WARNING: Data from COCO, DAV1, HOB2, KRAK excluded day 359.
WARNING: Data from KRAK excluded day 360.
WARNING: Data from GOLD, MADR, TIDB excluded day 361.
WARNING: Data from LPGS, PAMA, SNI1 excluded day 362.

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)
