Median Orbit Repeatability (see table below): 14.0 cm
                           (excluding deweighted satellites)

We continue to deweight data from PRN10 for this week.  Also, as orbit
solutions for day 350 (Dec 15, week 884) are not available at this time,
orbit repeatability statistics for day 349 are single-decimal precision
and reflect overlap with the previous day (348) 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: Data from PRN10 deweighted for the entire GPS week 883.
WARNING: Data from BRU1, CSN1, NOTO, WEST, WSMN excluded day 343.
WARNING: Data from GUAM, SHK1, STL3 excluded day 344.
WARNING: Data from CSN1, PIN1 excluded day 345.
WARNING: Data from HOB2, KELY, NYAL, POTM excluded day 346.
WARNING: Data from COCO, HOB2, KRAK, LPGS excluded day 347.
WARNING: Data from BRAZ, KRAK excluded day 348.
WARNING: Data from DAV1, KRAK, WETT excluded day 349.

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)
