______________________________________________________________________________
Median Orbit Repeatability (see table below): 10.0 cm
Data from PRN29 were mismodeled on days 261-263 and have been excluded
accordingly.
Although used in each day's analysis, we continue to deweight data from PRN13.
This satellite does not appear in any of the orbit products for 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: PIE1 (not ALGO) used as reference clock days 259-263.
WARNING: Data from PRN13 deweighted the entire GPS week 923.
WARNING: Data from PRN29 excluded days 261-263.
WARNING: Data from QUIN excluded day 257.
WARNING: Data from CSN1, KELY, KOUR excluded day 258.
WARNING: Data from CMP9, THU1 excluded day 260.
WARNING: Data from BLYT, KSTU, METS, TAEJ excluded day 261.
WARNING: Data from CAT1, METS excluded day 262.
WARNING: Data from SANT, TAIW excluded day 263.
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)
