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).

This week, we add a new candidate global station.  As with other sites,
this site is given the opportunity to participate in the orbit and clock
solution as the global site distribution varies.  The following nominal
coordinates were assumed:
                                  X (m)          Y (m)          Z (m)
YAR2 (Dongara, Australia)   -2389025.6983   5043316.9607  -3078530.6705

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 days 072, 073, and 078.
WARNING: FAIR (not USNO) used as reference clock day 074.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1053.
WARNING: Data from CHWK, DUBO, FLIN, GOL2, KELY, KOUR, MAD2, NANO, PERT, TID2,         UCLU, WHIT, WSLR, WTZT, PRN09 excluded day 072.
WARNING: Data from BRUS, CHWK, DUBO, FLIN, GOL2, KELY, MAD2, NANO, PETP, SPK1,         TID2, UCLU, USNO, WHIT, WSLR, WTZT excluded day 073.
WARNING: Data from AZU1, DGAR, GOL2, KELY, MAD2, NANO, PETP, SPK1, TID2, UCLU,         WHIT, WSLR, WTZT, PRN31 excluded day 074.
WARNING: Data from AMC2, AZU1, GOL2, MAD2, NANO, PETP, SOFI, SPK1, TID2, WHIT,         WTZT excluded day 075.
WARNING: Data from AZU1, GOL2, LHAS, MAD2, NANO, NOUM, PETP, RIOP, SANT, SNI1,         SPK1, TID2, WHIT, WTZT, PRN25, PRN30 excluded day 076.
WARNING: Data from FLIN, GODE, GOL2, KELY, LHAS, MAD2, NANO, PETP, TID2, UCLU,         WHIT excluded day 077.
WARNING: Data from CORD, FLIN, GOL2, LHAS, MAD2, NANO, PETP, TID2, UCLU, WHIT,         PRN02 excluded day 078.
