Median Orbit Repeatability (see table below): 6.0 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)

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 and PRN17 excluded the entire GPS week 1142.
WARNING: Data from DUBR, FORT, GODE, LBCH, SNI1, WHC1 excluded day 329.
WARNING: Data from DUBR, LBCH, PIMO, SNI1 excluded day 330.
WARNING: Data from DUBR, GALA, LBCH excluded day 331.
WARNING: Data from BJFS, DUBR, LBCH, MONP, PIMO, SIMO excluded day 332.
WARNING: Data from ALGO, DUBR, LBCH, PIMO excluded day 333.
