Median Orbit Repeatability (see table below): 7.0 cm

This week, we add one new candidate global station.  As with other sites,
this sites 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)
SIMO (Simonstown, South Africa)   5010435.8772    1670594.6180   -3563732.7186

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: Data from PRN15, PRN17 excluded the entire GPS week 1133.
WARNING: Data from PRN30 excluded day 270.
WARNING: Data from PRN02, PRN10 excluded day 271.
