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 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)
BJFS (Beijing, P.R.C.)      -2148743.9761   4426641.3759   4044655.9951
JAMA (Kingston, Jamaica)     1388059.8590  -5909149.1583   1951963.8339

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 days 325-330.
WARNING: NRC1 (not USNO) used as reference clock day 331.
WARNING: Data from PRN02 and PRN15 excluded the entire GPS week 1037.
WARNING: Data from AUCK, CASA, CEDU, CHAT, KOUR, MAC1, MAD2, MCM4, PETP, STR1,           TID2, VESL, WHIT excluded day 325.
WARNING: Data from CASA, KOUR, MAD2, NANO, NYAL, PETP, SNI1, UCLU, USNO, VESL,           WHIT, WSLR excluded day 326.
WARNING: Data from KELY, KOUR, MAD2, NANO, PETP, RAMO, SNI1, UCLU, WHIT, WSLR,           PRN14, PRN17 excluded day 327.
