Median Orbit Repeatability (see table below): 10.0 cm

Beginning this week, we add two 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)

SYOG (Syowa, Antarctica)           1766207.8738   1460290.3660  -5932297.7876

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 BILL excluded day 171.
WARNING: Data from BILL, BUCU, COCO excluded day 172.
WARNING: Data from COCO excluded day 173.
WARNING: Data from COCO, LHAS, TROM, WTZT excluded day 174.
WARNING: Data from CRO1, GLSV, WTZT excluded day 175.
WARNING: Data from PRN13, PRN15, COCO, CRO1, TOUL, WTZT excluded day 176.
WARNING: Data from PRN14, PRN15, ANKR, BILL, COCO, CRO1, TOUL, WTZT excluded             day 177.

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)
