Mean Orbit Repeatability (see table below): 16.7 cm

Beginning this week, we include data from several new stations.  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)

CMP9 (Firecamp 9, USA):       -2508501.8100  -4637190.4000   3579508.8400
LHAS (Lhasa, China-Tibet):     -106935.8468   5549268.6011   3139215.1909
LPGS (La Plata, Argentina):    2780103.4850  -4437418.5040  -3629404.7540

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 DAV1, GUAM, SPK1, VNDP, ZIMM excluded on day 183.
WARNING: Data from DAV1, FORT, GUAM, RCM5, VNDP, ZIMM excluded on day 184.
WARNING: Data from DAV1, FORT, GUAM, RCM5, ZIMM excluded on day 185.
WARNING: Data from DAV1, FARB, FORT, GUAM, RCM5, SPK1, TAIW, excluded on day 
         186.
WARNING: Data from DAV1, FARB, GUAM, SPK1, TAIW excluded on day 187.
WARNING: Data from DAV1, FARB, GUAM, ONSA, METS, SPK1, TAIW excluded on day 188.

LODR values in the adjacent column.  See IGS Report No. 1498 (jpl07827.sum)
