Mean Orbit Repeatability (see table below): 19.4 cm

According to the file nanu1995.mes obtained from the IGS CBIS, PRN22, was
unusable on days 158 and 159 (Jun 7, 8) due to maintenance/repositioning.
Data from this satellite did not meet our initial convergence criteria for
these days, and were excluded from our analyses accordingly.

Beginning this week, we include data from SPK1 (Saddle Peak CA, 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 = -2535988.3673 m, Y = -4642438.3100 m, Z =  3552159.6580 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 155.
WARNING: Data from KIT3, SHAO excluded on day 156.
WARNING: Data from LAMA, SHAO, TAIW excluded on day 157.
WARNING: Data from PRN22 excluded on days 158 and 159  due to a maneuver. 
WARNING: Data from GUAM, KIT3, LAMA, SHAO, TAIW excluded on day 158.
WARNING: Data from KIT3 excluded on day 159.
WARNING: Data from GUAM, TAIW, WETT excluded on day 160.
WARNING: Data from GUAM, TAIW excluded on day 161.

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)
