Median Orbit Repeatability (see table below): 8.0 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)
LAE1 (Lae, Papua New Guinea)  -5312857.1723    3451108.0486    -736322.7246
WTZA (Koetzting, Germany)      4075578.5341     931852.7596    4801570.0758

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 PRN02 excluded day 130.
WARNING: Data from PRN23 excluded day 131.
WARNING: Data from JAB1, KOUR excluded day 126.
WARNING: Data from CRO1, EPRT, PIMO, SSIA excluded day 127.
WARNING: Data from BILL, LBCH, SSIA, YAR1 excluded day 128.
