Median Orbit Repeatability (see table below): 9.0 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 167 microseconds was detected
for PRN16 at approximately 10:00 on day 064.
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 058, 060, 061, 063, 064.
WARNING: FAIR (not USNO) used as reference clock day 062.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1050.
WARNING: Data from GOL2, HOLP, LHAS, MAD2, TID2, WTZT excluded day 058.
WARNING: Data from BUCU, GOL2, HOLP, KELY, KOSG, LHAS, MAD2, NANO, NYA1, REYK, TID2, WTZT, PRN22 excluded day 059.
WARNING: Data from GOL2, HARV, HOLP, LHAS, MAD2, NANO, NICO, REYK, TID2, WTZT, PRN06, PRN07, PRN09 excluded day 060.
WARNING: Data from GOL2, HOLP, LHAS, MAD2, NANO, RIOP, TID2 excluded day 061.
WARNING: Data from AREQ, GOL2, LHAS, MAD2, NANO, TID2, WHIT, WSLR, PRN23 excluded day 062.
WARNING: Data from AREQ, FLIN, GLSV, GOL2, LHAS, MAD2, NANO, OBER, SOL1, TID2, UCLU, WHIT, WSLR, PRN23 excluded day 063.
WARNING: Data from CHWK, DUBO, FLIN, GOL2, MAD2, MAG0, NANO, PETP, SOL1, TID2, UCLU, WHIT, WSLR, PRN31 excluded day 064.
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)
