Median Orbit Repeatability (see table below): 9.0 cm

According to the file nanu1999.mes obtained from the IGS CBIS, PRN15 is
unusable as of day 153, pending further notice.  Data from this satellite
were mismodeled on days 158 and 162 and have been excluded from these two
days' analyses accordingly.  Data from PRN14 was mismodeled on day 162 and
has been excluded here as well.

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: GOL2 (not USNO) used as reference clock day 162.
WARNING: Data from PRN18 excluded the entire GPS week 1013.
WARNING: Data from COCO, CRO1, KIT3, RAMO, SCIP, TIXI excluded day 157.
WARNING: Data from PRN15, COCO, KIT3, NYA1, NYAL, RAMO, SCIP, TIXI, URUM                 excluded day 158.
WARNING: Data from CAS1, COCO, FORT, KIT3, RAMO, SCIP, URUM, WUHN, ZWEN                  excluded day 159.
WARNING: Data from COCO, FORT, KIT3, PRDS, SCIP, URUM, ZWEN excluded day 160.
WARNING: Data from COCO, FORT, PRDS, ZWEN excluded day 161.
WARNING: Data from PRN14, PRN15, CMP9, COCO, NSSP, PRDS, VENE excluded day 162.
WARNING: Data from CMP9, TORP, VENE excluded day 163.

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)
