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 42 microseconds was detected
for PRN30 at approximately 14:45 on day 340.

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: ALGO (not USNO) used as reference clock on days 339-341 and 343-345.
WARNING: NRC1 (not USNO) used as reference clock on day 342.
WARNING: Data from PRN02 and PRN15 excluded the entire GPS week 1039.
WARNING: Data from CEDU, DGAR, GODE, JAB1, KIRU, LHAS, MALI, PERT, TID2, VILL            excluded day 339.
WARNING: Data from ANKR, GODE, TID2 excluded day 340.
WARNING: Data from GODE, PETP, TID2 excluded day 341.
WARNING: Data from KELY, PETP, TID2 excluded day 342.
WARNING: Data from KELY, PETP, TID2 excluded day 343.
WARNING: Data from GODE, KELY, TID2, WES2 excluded day 344.
WARNING: Data from GODE, KOUR, NANO, SFER, TID2 excluded day 345.

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)
