Median Orbit Repeatability (see table below): 10.5 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.

Data from PRN13 were mismodeled this entire week, and those from PRN18 were
mismodeled on days 204 and 205.  These data have been excluded from the
corresponding satellite-days as accordingly.

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 PRN13 excluded the entire GPS week 1019.
WARNING: Data from BRUS, CARR, COCO excluded day 199.
WARNING: Data from BRUS, CARR, CMP9, COCO, FAIR, GLSV excluded day 200.
WARNING: Data from CARR, CMP9 excluded day 201.
WARNING: Data from CMP9, CRO1, ZIMM excluded day 202.
WARNING: Data from CRO1, NYAL excluded day 203.
WARNING: Data from PRN18, COCO, CRO1 excluded day 204.
WARNING: Data from PRN18, CAS1, COCO, NRC1, WTZR excluded day 205.

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)
