Median Orbit Repeatability (see table below): 14.0 cm

According to the file nanu1996.mes obtained from the IGS CBIS, PRN09 was
unusable on day 169 for maintenance (no maneuver).  Data from this satellite
were used in our analyses of this day, and a clock reset was detected at the
following approximate time:

      PRN09 - clock reset day 169 at 12:39:49  UT

Beginning this week, we include data from COCO (Cocos Island, Australia), and
HFLK (Innsbruck, Ausrtria).  As with most stations, these sites 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)
          COCO:    -741949.9875   6190961.7367 -1337768.6589
          HFLK:    4248505.1695    855575.6006  4667172.2047

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: NLIB (not ALGO) used as reference clock days 171 and 172.
WARNING: FAIR (not ALGO) used as reference clock day 173.
WARNING: Data from CMBB, HFLK, MATE, OHIG, USC1, YELL excluded day 168.
WARNING: Data from DAM2, DGAR, HFLK, LBCH, MATE, NYAL, YELL excluded day 169.
WARNING: Data from DAM2, LBCH, MATE, YELL excluded day 170.
WARNING: Data from DAM2, DGAR, KELY, ZWEN excluded day 171.
WARNING: Data from CMP9, DAM2, DGAR, GOLD excluded day 172.
WARNING: Data from ALGO, BOR1, CMP9, DGAR, MADR, QUIN, SPK1, USC1, WSMN                  excluded day 173.
WARNING: Data from BOR1, CHIL, CMP9, DAM2, OHIG, SPK1, WEST excluded day 174.

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)
