Mean Orbit Repeatability (see table below): 33.4 cm

There were little or no data available for PRN01 (GPS32) from stations used in
the global analysis for day 129 (May 9).  This satellite is absent from the
corresponding orbit file for this day (jpl08002.sp3).  Also, there was an
apparent clock reset at ALGO on this day as well; NLIB was instead used as
the reference clock for this day.

Beginning this week, we begin to include data from WMSN (Whitesands NM, USA).
As with most stations, this site is given the opportunity to participate in the
orbit and clock solution as the global site distribution varies.  The following
nominal coordinates were assumed:

       X = -1517583.0942 m, Y = -5172994.5254 m, Z =  3399248.4809 m

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 KIT3, TAIW excluded on day 127 (May 7).
WARNING: Data from TAIW excluded on day 128 (May 8).
WARNING: Data from TAIW excluded on day 129 (May 9).  NLIB (not ALGO) used as
         a reference clock on this day only.  No data available for PRN01 on
         this day.  
WARNING: Data from HOB2, TAIW excluded on day 130 (May 10).
WARNING: Data from KOSG, MATE, TAIW excluded on day 131 (May 11).
WARNING: Data from CICE, MATE, TAIW excluded on day 132 (May 12).
WARNING: Data from KIT3, SHAO, TAIW, TSKB excluded on day 133 (May 13).

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)
