Median Orbit Repeatability (see table below): 11.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).

A large clock discontinuity (reset) of about 338 microseconds was detected
for PRN07 at approximately 17:20 on day 335.  Additionally, it appears that
the drift of the clock onboard PRN24 experienced a shift from about -11 ps/s
to +21 ps/s at approximately 12:45 on day 336.

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: NRC1 (not USNO) used as reference clock day 332.
WARNING: ALGO (not USNO) used as reference clock days 333-338.
WARNING: Data from PRN02 and PRN15 excluded the entire GPS week 1038.
WARNING: Data from BAHR, CORD, LPGS, MAD2, MAG0, PETP, TROM excluded day 332.
WARNING: Data from AMC2, CORD, GODE, HERS, KOUR, LPGS, MAD2, SANT, USNO, VESL            excluded day 333.
WARNING: Data from CORD, GOUG, LHAS, LPGS, SANT, TID2, VESL, PRN14 excluded              day 334.
WARNING: Data from LHAS, TID2 excluded day 335.
WARNING: Data from CASA, CRO1, DGAR, LHAS, TID2 excluded day 336.
WARNING: Data from CASA, LHAS, TID2 excluded day 337.
WARNING: Data from CASA, JAB1, KOKB, LHAS, MALI, TID2 excluded day 338.

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)
