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).

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)
AMMN (Amman, Jordan)         4386124.5807   3172638.1624   3363685.2466
KODK (Kodiak, AK, USA)      -3027465.2924  -1575906.2581   5370078.0493 

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 day 106.
WARNING: Data from PRN14, PRN15, and PRN18 excluded the entire GPS week 1057.
WARNING: Data from PRN05, PRN19, PRN30 excluded day 100.
