Median Orbit Repeatability (see table below): 7.0 cm

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)
NVSK (Novosibirsk, Russia)          433606.1044    3655562.0899    5191291.7709
RABT (Rabat, Morocco)                5255617.8592    -631745.7752  3546322.5539

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 excluded the entire GPS week 1099.
WARNING: Data from PRN06 excluded days 032 and 033.
WARNING: Data from AZU1, DARW, ESTI, HOLC, LBCH, PETP, SELE, SYOG, WTZT                  excluded day 028.
