Median Orbit Repeatability (see table below): 10.0 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 0.5 microseconds was detected
for PRN16 at approximately 10:20 on day 050.

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 days 044-047.
WARNING: NRC1 (not USNO) used as reference clock days 049-050.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1049.
WARNING: Data from GOL2, KELY, MAD2, NANO, NOUM, PERT, VILL excluded day 044.
WARNING: Data from CHWK, GOL2, MAD2, QUIN, SNI1, TID2, PRN08 excluded day 045.
WARNING: Data from DAV1, GODE, GOL2, HARV, MAD2, PETP, TID2 excluded day 046.
WARNING: Data from GOL2, MAD2, PETP, TID2 excluded day 047.
WARNING: Data from GODE, GOL2, IRKT, MAD2, QUIN, TID2, PRN02 excluded day 048.
WARNING: Data from BRUS, GOL2, IRKT, LHAS, MAD2, TID2 excluded day 049.
WARNING: Data from BARB, GOL2, IRKT, RIOP, TID2, WHIT, PRN06, PRN13 excluded             day 050.

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)
