Mean Orbit Repeatability (see table below): 17.9 cm

There were no data from ALGO on day 120 after 14:04:30 UT.  Because of this
data gap, we have used NLIB as a reference clock on this day only.

Beginning this week, we include data from five new sites, listed below.  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)

    HBRK (Hillsboro KA, USA):  -636268.6900  -4971317.6976  3932307.2268
    HKLO (Haskell OK, USA):    -529854.4554  -5159660.9390  3699802.5177
    THU1 (Thule, Greenland):    538980.4736  -1388713.7007  6180995.9180
    VCIO (Vici OK, USA):       -826817.6403  -5095178.6300  3735008.9607

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 CASA excluded on day 120 (Apr 30).  NLIB (not ALGO) used as           reference clock on this day only.
WARNING: Data from JOZE, LAMA excluded on day 121 (May 1).
WARNING: Data from KIT3, LAMA, SHAO excluded on day 123 (May 3).
WARNING: Data from KIT3, SHAO excluded on day 124 (May 4).
WARNING: Data from KIT3, TAIW excluded on day 126 (May 6).

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)
