Median Orbit Repeatability (see table below): 10.5 cm

Data from PRN18 were mismodeled on day 285 and have been excluded accordingly.

Please note that results for day 291 (week 980, day 0) are not currently
available.  As such, orbit repeatabilities in the table below for day 290
reflect comparisons with day 289 only.

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: PIE1 (not USNO) used as reference clock days 284 and 285.
WARNING: NRC1 (not USNO) used as reference clock days 286.
WARNING: Data from DHLG excluded day 284.
WARNING: Data from PRN18, COCO, DHLG, HARK, HOB2, LPGS excluded day 285.
WARNING: Data from BARB, HARK, LPGS excluded day 286.
WARNING: Data from COCO, HARK, HOB2, HOLC, IRKT, LPGS, NYAL excluded day 287.
WARNING: Data from COCO, LPGS excluded day 288.
WARNING: Data from COCO, KERG excluded day 289.
WARNING: Data from COCO, HOB2, LPGS excluded day 290.

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)
