Median Orbit Repeatability (see table below): 12.0 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 4 microseconds was detected
for PRN16 at approximately 18:30 on day 065.

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 065-067, 069, and 070.
WARNING: NRC1 (not USNO) used as reference clock day 071.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1052.
WARNING: Data from CHWK, DUBO, FLIN, GOL2, KELY, MAD2, MAG0, NANO, PETP, SOL1,           TID2, TUBI, UCLU, WHIT, WSLR excluded day 065.
WARNING: Data from CHWK, DUBO, FLIN, GOL2, KELY, MAD2, NANO, OBER, PETP, TID2,           UCLU, USNO, WHIT, WSLR, PRN07, PRN10 excluded day 066.
WARNING: Data from CHWK, DARW, DGAR, DUBO, FLIN, GOL2, KELY, MAD2, NANO, TID2,           UCLU, WHIT, WILL, WSLR, PRN06, PRN08 excluded day 067.
WARNING: Data from CHWK, DUBO, FLIN, GODE, GOL2, KELY, MAD2, NANO, OBER, TID2,           UCLU, WHIT, WILL, WSLR, PRN08 excluded day 068.
