Median Orbit Repeatability (see table below): 7.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).

According to the file ftp://tycho.usno.navy.mil/pub/gps/gpstd.txt, PRN14
was removed from service on day 105.

This week, we add two new candidate global stations.  As with other sites,
these sites are 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)
NKLG (Livreville, Gabon)     6287388.9677   1071574.9489     39132.7822
TID1 (Canberra, Australia)  -4460996.3219   2682557.1214  -3674443.6640

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: DRAO (not USNO) used as reference clock days 107 and 108.
WARNING: NRC1 (not USNO) used as reference clock day 109.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1058.
WARNING: Data from PRN09 excluded day 107.
WARNING: Data from PRN01, PRN08, PRN27 excluded day 109.
WARNING: Data from PRN05 excluded day 112.
WARNING: Data from AMMN, GOL2, MAD2, NANO, TID2, UCLU, USNA, WHIT, WTZT                  excluded day 107.
WARNING: Data from AMC2, AMMN, CORD, GOL2, JAB1, MAD2, NANO, TID2, USNA, WHIT,           WTZT excluded day 108.
WARNING: Data from GOL2, JAB1, KUNM, MAD2, NANO, PETP, TID2 excluded day 109.
WARNING: Data from GOL2, JAB1, MAD2, NANO, PETP, TID2 excluded day 110.
