Median Orbit Repeatability (see table below): 10.0 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 a 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)
TUBI (Gebze, Turkey)         4211318.4413   2377866.3759   4144664.2137

A large clock discontinuity (reset) of about 578 microseconds was detected
for PRN26 at approximately 08:45 on day 351.

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: ALGO (not USNO) used as reference clock the entire GPS week 1040.
WARNING: Data from PRN15 excluded the entire GPS week 1040.
WARNING: Data from KOUR, MAD2, NANO, TID2, WHIT, PRN02 excluded day 346.
WARNING: Data from BRUS, CRFP, JAB1, KELY, MAD2, MALI, NANO, TID2, WHIT,
         PRN23, excluded day 347.
WARNING: Data from BRUS, CRFP, JAB1, MAD2, NYAL, TID2, PRN05, PRN10 excluded             day 348.
WARNING: Data from BRUS, CRFP, FAIR, JAB1, RIOP, TID2, WLSN excluded day 349.
WARNING: Data from BRUS, FAIR, HARV, JAB1, MAD2, SUWN, TID2, WLSN excluded day           350.
WARNING: Data from JAB1, LHAS, MAD2, MATE, SUWN, TID2 excluded day 351.
WARNING: Data from CASA, HERS, KOUR, MAD2, MATE, TID2, PRN14, PRN16 excluded             day 352.
