Median Orbit Repeatability (see table below): 16.0 cm
                           (excluding deweighted satellites)

We continue to deweight data from PRN10.  Solutions for this satellite are
not included in our sp3 orbit products this week.

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: NLIB (not ALGO) used as reference clock days 332 and 333.
WARNING: PIE1 (not ALGO) used as reference clock days 334 and 335.
WARNING: Data from PRN10 deweighted for the entire GPS week 881.
WARNING: Data from CSN1, HBRK, LMNO excluded day 329.
WARNING: Data from CASA, CSN1, KRAK, STJO, TROM excluded day 330.
WARNING: Data from CASA, KRAK, SANT, STJO excluded day 331.
WARNING: Data from CASA, CMBB, CSN1, POL2, STJO, WTZR excluded day 332.
WARNING: Data from CSN1, DAV1, HOB2, STJO, WTZR excluded day 333.
WARNING: Data from KRAK, WTZR excluded day 334.
WARNING: Data from CSN1, KRAK, WTZR excluded day 335.

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)
