Median Orbit Repeatability (see table below): 8.0 cm

This week, we add three new candidate global stations.  As with other sites,
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)
HARB (Pretoria, South Africa)      5084660.1387    2670326.3467   -2768482.6263
SLOR (San Lorenzo, Honduras)        277528.9454   -6198801.9087    1471065.5687
SSIA (San Salvador, El Salvador)     95566.9680   -6197785.6770    1500590.5323

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: DRAO (not USNO) used as reference clock day 303.
WARNING: ALGO (not USNO) used as reference clock day 304.
WARNING: NRC1 (not USNO) used as reference clock days 305-309.
WARNING: Data from KELY, LBCH, PETP, WTZT excluded day 303.
WARNING: Data from JAMA, LBCH, PETP, WTZT excluded day 304.
WARNING: Data from KELY, NICO, PETP, WTZT excluded day 305.
WARNING: Data from FORT, JAMA, KELY, LBCH, PETP, SOFI, WTZT excluded day 306.
WARNING: Data from KUNM, LBCH, NOUM, PETP excluded day 307.

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