Median Orbit Repeatability (see table below): 12.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae, namely: BAKO BZRG GOPE HOFN INEG JOZE MATH MDVO PENC WTZT.

Beginning this week, we add a few new candidate global stations.  As with
other sites, these stations 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)

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: NRC1 (not USNO) used as reference clock day 234.
WARNING: PIE1 (not USNO) used as reference clock days 235-237.
WARNING: DRAO (not USNO) used as reference clock days 238 and 239.
WARNING: ALGO (not USNO) used as reference clock day 240.
WARNING: Data from RAMO excluded day 234.
WARNING: Data from RAMO, TOUL excluded day 235.
WARNING: Data from PRN30 excluded day 236.
WARNING: Data from PRN29, HERS, MEDI excluded day 237.
WARNING: Data from PRN15, PRN29, CASA, HERS excluded day 238.
WARNING: Data from PRN15, PRN23, ANKR, JAB1 excluded day 239.
WARNING: Data from PRN15, PRN23, JAB1, PIN1, TROM excluded day 240.

In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column.  See IGS Report No. 1498 (jpl07827.sum)
